Violet light is deviated most and red light is deviated the least on passing through the prism.

Text Solution

Verified by Experts

i. Different colours travel with different speed in prism.
ii. Hence, refractive index of prism is different for different colours. It is maximum for violet light and minimum for red light.
iii. The angle of deviation of ray of light on passing through a prism depends on the refractive index of the material of the prism. Hence, violet light is deviated the most and red light is deviated the least on passing through a prism.
