How does a DVD separate white light into different colors?

Diffraction, the lines are so close together that they approach the wave length of the various colors of visible light.

(Note, some insects and birds get their coloring this way too.)

What white light separate into different colors?

A prism


How white light produced different colors?

White light doesn't produce different colors. The only way to make white light is tocombine light with all of the different colors. So if you already have white light, allof the colors are already there. You only have to separate them in order to see them.


What device is used to separate the white light to different colors?

A prism.


How does a prism works to separate the colors in white light?

White light has all visible frequencies incorporated in it. A prism refracts different frequencies at different angles so the different frequencies (colors) spread out.


What happens to white light as it travels through a prism?

The light is refracted (bent) causing it to separate into different colors.


How does refraction can separate white light into color?

The reason white light is separated into colors is because light of different colors have slightly different indices of refraction. Thus, for example, red light might be bent a little bit more than blue light.


What separates white light into it various colors?

White light appears white because it is a conglomeration of all the different wavelengths of light. A prism will separate the different wavelengths because they refract (or bend) at different angles through the prism.


How do you make a rainbow from white light?

White light contains all wavelengths of colors. To make a rainbow, you need to separate those wavelengths (colors). This is accomplished by bending, or diffracting light. Different wavelengths of light are bent differently when they are passed through a transparent prism. When they are bent diffrently, they start to separate from one another and become visible to the eye as different colors.


Refraction can separate white light into what?

Refraction can separate white light into the spectrum of visible light from red to violet.


Why is a prism able to separate the colors of white light?

A clear glass prism (and rain drops in the sky on a sunny day) are able to separate white light into the colours of the rainbow. The basic reason is that white light is reflected at different angles because of the different wavelengths.


How do prisms work?

Refraction is when light bends through an object. White light is made up of all the colors of the spectrum. Different colors have different wavelengths, therefore they bend at different angles. So when white light passes through a prism the different colors bend at different angles, so they separate to produce the rainbow of light that we see.


All of the colors in white light are visable when white light is?

Yes, although the separate colors are perceived to your eye as white. If you have a prism you can separate white light into the continuous color spectrum. This effect is also achieved in rainbows.
