What Is the Rainbow Color Order Understanding ROYGBIV

What Is the Rainbow Color Order Understanding ROYGBIV SAT / ACT Prep Online Guides and Tips You’ve more than likely seen a rainbow aftersome rain on a sunny day. But what are the colors of the rainbow in order? And what causes a rainbow to form? We’ll explain everything you need to know about the rainbow color order, including what ROYGBIV means, why rainbows exist, and whether or not the rainbow order will ever change. What Are the Colors of the Rainbow in Order? Officially, therainbow color order is as follows: Red Orange Yellow Green Blue Indigo Violet This means that every rainbow you see will have these seven colors in this order (from the top of the arc of the rainbow to the bottom of the arc). The easiest way to remember therainbow color order is to use the mnemonic device ROYGBIV, in whicheach letter stands for the first letter of the color names (in other words, R is for red, O is for orange, Y is for yellow, etc.). Most people pronounce ROYGBIV in three syllables, making it sound and look more like the name of someone: Roy G. Biv. Occasionally, you might see ROYGBIV written in reverse as VIBGYOR. I'm willing to bet you can readily envision most, if not all, of these seven colors of the rainbow. But many people get confused about the color indigo and how it differs from blue and violet. Typically, indigo is described as being abouthalfway between blue and violet. Most people seem to agree that indigo is closer to a deep or dark blue than it is a more purple or violet color, but there's still debate even about this! What Is a Rainbow? What Causes One to Form? You now know the rainbow color order, but what exactly causes a rainbow to form? And why does a rainbow contain these seven colors in this order specifically? To answer these questions, we'll go all the way back to English scientist and mathematician Isaac Newton. Newton conducted many experiments with light, which are summarized in his 1704 book Opticks, and discovered that when clear white light passes through a prism, it refracts into different colors in a particular order, or what we know as a rainbow. This means that white light is not actually white but is composed of a humongous spectrum of colors! These colors make up the visible (light) spectrum; it's the part of the electromagnetic spectrum that human eyes can see. All colors in the visible light spectrum travel at different wavelengths, with red having the longest wavelength at around 700 nanometers and violet having the shortest at around 380 nanometers. These wavelengths bend at different angles when passing through a prism, and this is what causes the rainbow color order to look the way it does. Newton is the one who decided to interpret the rainbow order in terms of seven unique colors- ROYGBIV- but the truth is that rainbows consist of more than a million colors, many of which are invisible to the human eye! In addition, some colors, such as pink and brown, are indeed visible to the human eye but do not have their own wavelengths and can only be made when combining certain wavelengths. For example, pink is created by combining red, green, and blue wavelengths. So how is a natural rainbow made- you know, those rainbows we see in the sky? Rainbows form naturally when sunlight passes through water droplets in the sky, causing the light to refract and reflect, typically in the form of an arc. Therefore, your chance of seeing a rainbow will be highest on sunny, rainy days. Rainbows always appear opposite the part of the sky the sun is in, so if you’re trying to look for a rainbow, you'll want to make sure that your back is to the sun. Will the Rainbow Color Order Ever Change? When we talk about the rainbow color order,most peoplethink of ROYGBIV. But as I mentioned above, there are actually a lot more than just seven colors in the rainbow. Newton chose to define the rainbow as consisting of seven colorsbecause he believed the number of colors in a rainbowshould be the same as the number of notes in a musical scale. Clearly, this is a pretty arbitrary (and non-scientific way) to look atthe different colors in a rainbow. Indeed, many people still struggle to distinguish indigo from violet and blue! So while the actual rainbow color order (the visible spectrum) will always be the same, the way we talk about the rainbow color order could change over timedepending on how people view and choose to define colors. Many modern portrayals of the rainbow have just six colors- red, orange, yellow, green, blue, and violet- opting to leave out indigo entirely. For example, the LGBT rainbow flag goes directly from blue to violet, without indigo. The LGBT rainbow flag at a gay pride parade. So why do we still include indigo in the rainbow color order, especially if so many people think of it as nothing more than a transitional color between blue and violet? Many believe it is merelydue to the desire towant to stick to tradition. Nevertheless,it's certainly possible that future kindergartners will learn about ROYGBV- minusthe I for indigo! What’s Next?

Aids in Africa Essay

Aids in Africa Essay Aids in Africa Essay Much Ado about Nothing is a comedy play set in a patriarchal time written by Shakespeare. It is based on deception, allusion and finally reconciliation. Don John causes and spread lies that the rest of the characters have to sort out but like most Shakespearean plays, it all end well. The nefarious character has been captured and the non-culpable characters have been righted. Benedick acts very obnoxious and whimsical in the first two scenes by being very immature and narcissistic whereas Beatrice acts very manipulative and witty. However in Act 4 Benedick acts completely different. Firstly Benedick is shown to be more mature in Act 4 scene 1: 'Surely I do believe your fair cousin is wronged' Here Benedick is trying to calm down Beatrice and for once is agreeing that Beatrice's cousin has been 'wronged'. This is very strange because throughout the play Benedick 'skirmish of wit' with Beatrice has involved him acting harshly but now he is acting as a manly figure, by trying to figure out what is happening and he is starting to convince Beatrice that Hero is innocent and that she should not â€Å"weep†. Another example is when Benedict asked Beatrice 'Is Claudio thine enemy'. Here, we can see that Benedick is more mature as he is making Beatrice see and act clearly because Benedick has to make sure what she is doing and that she doesn't react irrationally by asking Beatrice if Claudio is an 'enemy'. By calming and maturely he has started earning the love that Beatrice deserves. After he takes on the task to challenge Claudio, he acted very mature by telling to Beatrice to 'go comfort your cousin’; this is very affective because he uses an imperative. By doing this he is taking a leadership stance, his maturity is also displayed in his caring attitude as he directs Beatrice to look after Hero, who has been emotionally hurt by Claudio words. In contrast to this earlier in the play Benedick was a very immature buffoon by saying 'if signor Leonato be her father, she would not have his head on her shoulders'. Here Benedick is acting immature by insulting Leonato by saying Hero is not his daughter, this is a worse in Shakespearean times because you could not tell who was the father, so Benedick has insulted Leonato. This is very different from Act 4 scene 1 because he takes leadership and tries to work out what is really happening and who is to blame. In the 1993 version, Branagh adds to Benedick's presentation as being more mature through his reactions when Beatrice was crying. He raised his arms and held her back so Beatrice can calm down. This shows an increase of maturity as he takes on the role to calm Beatrice down to stop her acting drastically and the she will listen to him. Secondly, Beatrice is frustrating with her role is demonstrated in Act 4 scene 1: 'O God [†¦] I would eat his heart in the market place' Here Beatrice is using vengeful diatribe towards Claudio when she states that she would 'eat his heart'. This shows that Beatrice wants to get revenge from Claudio for being so nasty to hero and so she sees him as evil. Beatrice wants to complete this horrible task in the 'market place' so everyone can watch of what has become of the Claudio. Beatrice is showed to be frustrated with her by saying ' I cannot be a man with wishing; therefore I will die a woman with grieving'. Here we can see that Beatrice feels upset but she is helpless because she can't do anything about it because 'she will never be a 'man with wishing'. A man, like Benedick is very important to Beatrice because she wants vengeance for what Claudio has done but she needs Benedick to fulfil this task because being a woman she can only 'grieve'. She will never be a woman she will try and manipulate Benedick into duelling Claudio by stating 'Ah, how much might the man deserve of me that would right her'. Here Beatrice i s trying to manipulate Benedick into duelling Claudio cannot do it herself so she needs convince Benedick into the man that will deserve

Differences in Management Styles between the American and the Japanese Dissertation

Differences in Management Styles between the American and the Japanese in Multinationals - Dissertation Example The emergence of Japan in the 1980s as America's foremost industrial opponent seems to have persuade a kind of moral panic in business with the Japanese cast in the role of 'folk devils'. The implicit assumption that America had the best management system in the world was now noticeably in question, and from an American perception this seemed appalling. In addition, if Japanese management was indeed effective but could not be transferred to American) firms, then the future for American business seemed miserable. The problem of learning from Japan proved, however, to be intricate, and it has raised difficult questions of fact and worth. In some points of the dispute evidence has been tough to come by whilst in others there have been sharply divergent understandings of the data. A case in peak is the impact of the Japanese system on Japanese employees. Should the Japanese worker be regarded as a devoted, protected, contented employee embraced by a humanistic organizational culture which promotes pride of work and company loyalty as Ouchi's Theory Z proposes? Or is he better seen as a gloomy robot tied to a life of unending toil by an authoritarian management system and a disciplinary set of social values that suppress individuality and bump up conformity as a supreme end, a vision characterized as Theory F = Fear?. Such queries cannot be replied by facts solely because even facts must be construed. At this spot cultural assumptions and values are likely to go into the debate so raising questio ns concerning what the facts mean. Can the Japanese management system be shifted to the United States? It looks as if it can, if only partly. The evidence so far suggests that both the advocates and the detractors of learning from Japan have clasped some portion of the truth. It has been quench agreed on all sides that the Japanese must be doing something right.
