As we know there are seven color in a light. It travels in a same velocity when it passes through air, but when it passes through prism different color travels with different velocity, as a result the emergent light is seen in seven color. Ther are; voilent,indigo,blue,green,yellow,red,orange.....
because when light hits the prism the prism scatters the light in all directions there for you can see the rainbow
I believe that you are talking about a prism, and the process where the light is broken up in to its constituent parts is called dispersion
red light is monochromatic light and if it shines on a prism its still red light pass through the prism, not 'rainbow' color.
A device for separating light into different colors is know as a ?
All the colors of the visible light spectrum are made visible.
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.

Enter the light perpendicular to the hypotenuse of the Prism above or below the center of the hypotenuse. The light will reflect off the two non-hypotenuse sides and reflect back out in the opposite direction, 180 de Save grees.
the prism can obtained coloured of light in prism due to disperion of light
When ordinary visible light shines on a prism.

It is named after the type of prism used in the instrument. A constant deviation prism has the property that the angle between light entering the prism (the incident light) and light exiting the prism (the emergent light) is always the same, no matter what the angle of the incident light to the prism.
As the light passes through the prism, the resulting effect is called a 'refraction'. In other words, the light enters from one side of the prism and is then 'redirected' at a right angle as it exits the prism.
red light is monochromatic light and if it shines on a prism its still red light pass through the prism, not 'rainbow' color.
