Why do the colors of the rainbow come out of a prism?
A rainbow results only when "white light" shines through it. White light is a combination of light of many different wavelengths (we see different wavelengths as different colors). Each wavelength is refracted (bended) at a slightly different angle, separating the different colors for us to see.
Can refracted light be refocused back to white light?
Yes, it certainly can. There are many simple arrangements to do so. The classic example is the diffused light that passed through a prism, when passed through another prism it is restored to its original characteristics.IMPROVEMENT:The aforesaid classic method works only if the second prism is placed in a reverse way (upside-down as compared to the first). What happens is that the white light that gets split in the first prism, de-splits when it passes through the second prism resulting in getting back the original white light.
Why you see different colors in white light?
This really seems strange, doesn't it? Remember that mixing light of various colors is different from mixing pigments of various colors. It's easy to see that if we had a very bright white paint, then mixing paints of various colors into it will only result in something other than white. Also, there is nothing you can do to the white paint to extract out of it paint of any spectrum color. With light it is different. Think of white light as if it were sound static, or 'white noise'. White light comes from the complex waves caused by the mix of all the light frequencies in the visible range of electromagnetic radiation. That's why you see a rainbow effect when you pass white light through a prism. The prism causes a 'spreading out' of the light of varying frequency that is inherent in the white light.
What will happen if we replaced sodium lamp to white source in newton ring experiments?
if white light is used in place of monochromatic light, a few coloured rings are observed. each colour gives rise to its own system snd it gives a rainbow type illuminetion. tjese rings soon superimpose and result in uniform illumination
Can diffraction be produced with white light or only with monochromatic light?
With white light, rainbows are an example.
Does the colour of incoming light affect the pattern of the prism?
Sure. The prism just spreads out the wavelengths that enter it. No color can come out of the prism that didn't go into the prism. When white light goes in, you see all colors come out, because white light is a mix of all colors. But if the light that entered the prism was a mix of only red and blue, then all you'd see come out would be a red stripe and a blue stripe, with no light in between them.

How can you change the color of white light?
White light is made up of all the colours in the spectrum. This can be proved by passing a ray of white light through a prism. As the light passes through the prism it will be split into the colours of the rainbow. Making a rainbow is one way of changing the colour of white lite. Another way is to filter the light - if you shine white light through a red filter then only the red bit of the white light will pass through, turning the light beam into a red beam.
What statement correctly identifies a sound wave?
A beam of sunlight falling on a prism refracts and forms seven color bands. This illustrates that A) white light is the absence of color. B) white light is made up of seven different colors. C) only a prism can split sunlight into seven colors. D) the light coming out of the prism is not sunlight.
If a laser beam consists of light of only a single color will it produce a spectrum of colors when it passes through a glass prism?
No. Monochromatic light (light of a single color) will pass through the prism without dispersing. White light disperses into its constituent colors as it passes through a prism, and we therefore observe the different colors emerging in a dispersal pattern as the light emerges from the opposite side of the prism. Since monochromatic light is made up of only one color, there are no colors to disperse, and so the beam of light passes through the prism coherently.
How is white paper seen. In science we did about seeing red paper. He said all the colours of the rainbow come from a source of light and then only red reflects off the paper. How is white different?
White light is simply pure light; it is a mix of all the colors of light. You can test this by putting a crystal prism near a light and admiring the rainbow. The prism has separated the white light into all its different colors. We can see white things, like bleached paper, because it simply reflects nearly all light, therefore appearing as white to us. Of course, even paper isn't perfect. It has ridges and texture. The tiny, tiny shadows that lie in these ridges help our eyes to recognize an object is sitting in front of us.

When blue light goes through a prism what happens?
Blue light enters the prism and is refracted (bent) by the glass and emerges as blue light on the other side. Blue light is bent (refracted) most due to its slow(er) speed than say Red light which is faster and has a longer wavelength. Newton did an experiment like this and concluded that white light was made up of different colours of light together. Shine a white light through a prism and it will emerge as all the colours of the rainbow. Blue light is unchanged as it consists only of blue light Answered by Chris Banks.
What is dispersion of white light?
White is not a colour. It is sensed only by human eye. Actually white is a composite of many colours. Such a composite white light could be spilit up by using a triangular prism. This splitting of composite white light into its constituent colours is called dispersion.

How do you find a Prism Scale in SoulSilver?
You can only get them in the Black & White, Black 2 & White 2.
Why does dispersion take place in only a prism and not in a glass slab?
The light strikes on one surface of the prism undergoes refraction and passes through the glass of the prism, and when emerges out, it refracts again. This causes the dispersion of the light and splits the light into its constituent colours. The degree of bending depends on the angle at which the ray of light enters and leaves the faces of the prism. The faces of the prism are not parallel to each other. For a glass slab, the opposite faces of the slab are parallel. So only a slight deviation occurs.
