When white light(composite light) consisting of various colors is passed through a prism, light of different colors will be deviated through different angles. Since the deviation is related to refractive index and refractive index to the color of light the deviation produced for different colors are different for same prism.That is the refractive indices are different for the various colors and this difference in the refractive indices is responsible for dispersion.

White light is dispersed when it passes through a prism. It is then separated into its component colors, which are red, orange, yellow, green, blue, indigo and violet.

Newton discovered that the colors formed by a prism can be recombined to create light?

He discovers what is known as the rainbow, by using a prism to show that light is made up of all of those colors.


How does a prism allow us to see more than just white light?

I got this ! A prism allows you to see more then just white light because the sun reflects to the prism and then that light gets absorbed and reflected back into our eyes to see all the colors of the spectrum.


What tools can be used to break up white light?

Breaking of white lights means dispersion of light in which the white light or the visible light splits into 7 colors. Many tools may be used to break up the white light but among them one of them is Prism. It can break up the white lights into 7 colors. Keep a white paper in front of the prism and the prism in the sun due to which the sunlight coming from the sun passes through the prism and the white breaks up into 7 colors due to change in velocity of the different invisible lights inside the white or the visible light. Other tools like plastic scale or ruler also can be used to break up the white light. Thank you


How can you prove that white light contains a mixture of light with different colors?

A simple diffraction device would show that white light contains a mixture of light of other wavelengths. If you want to see it yourself, you could buy a pair of basic diffraction glasses, or a similar instrument, for under $10.


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.
