. Draw a diagram to show the dispersion of white light by a glass prism. What is the cause of this dispersion

Best Answer

Ans. – The spilling up of white light into seven colours on passing through a transparent medium like a glass prism is called dispersion of light.


-We get different colour of light when white light is passed through a glass prism because white light is a mixture of lights of seven colours: red,  orange, yellow, green, blue, indigo and violet. The  dispersion of light occurs because the

angle of refraction ( or angle of bending ) of lights of different colours is different when passing through the glass prism
