Question

state the dependence of angle of deviation?
1.on the Refractive index of material of prism

2.on the wavelength of light
​

Answer 1

Answer:

Explanation:

(i) For a given angle of incidence, the prism with a higher refractive index (e.g. flight glass) produces a greater deviation than the prism which has lower refractive index (e.g, crown glass).

(ii) Angle of deviation decreases with the increases in the wavelength of light.

Angle of Deviation∝  1/wavelength
