Answer 1

Explanation:

These colors are often observed as light passes through a triangular prism or a transparent ruller. Upon passage through the prism, the white light is separated into its component colors - red, orange, yellow, green, blue and violet. The separation of visible light into its different colors is known as dispersion.

Answer 2

Answer:

it is called dispersion of light

Explanation:

Dispersion of light: The splitting of white light into seven colours on passing through a transparent medium is called dispersion of light. The dispersion of white light happens because the angle of refraction of lights of different colours is different while passing through the transparent medium.
