Question

1. What do you understand by minimum deviation?

2. How does the angle of minimum deviation produced by a prism change with
(a) decrease in wavelength of light and
(b) increase in refracting angle of prism?​

Answer 1

Answer:

1: A method for measuring the refractive index of a prism or a liquid in a hollow prism by determining the minimum deflected angle of a light beam.

2:a)Shorter wavelengths travel more slowly through the prism and hence are further deviated as compared to longer wavelengths. Hence, angle of deviation decreases with increase in wavelength

b)As we increase the wavelength, angle of deviation decreases. The angle of deviation increases with the increase in the angle of prism
