Question

If violet light incident at 30⁰ to a prism is deviated by 28⁰, then choose the correct option for deviation of green light and red light at the same angle of incidence(30⁰)

Answer 1

Answer:

c) 25 deg (G) 20 deg

Explanation:

This is because the violet colour deviates the most and the red colour deviates the least. Thus, the deviation of the red colour will be less than the deviation of green and violet colour.
