A ray of light incident at an angle 48° on a prism of refracting angle 60° suffers minimum deviation.

Changes in the angle of deviation as we increase (i) The wavelength of incident light As we increase the wavelength, angle of deviation decreases. (ii) The refracting angle of the prism The angle of...

The relation between the angle of incident (i), angle of emergence (e), angle of prism (A) and angle of deviation (δ) for a ray of light passing through an equilateral...

(i) i2 = i1 (ii) Angle of deviation is minimum Explanation: In minimum deviation position, the refracted ray inside the prism travels parallel to it if the prism is equilateral and the...

The angle of deviation (δ) increases with the increase in the angle of prism (A).

The light ray bends at both the surfaces of prism towards its base.

The deviation produced by the prism does not depend on the size of prism.

Given, Angle of prism, A = 60° Angle of minimum deviation, = 36° Angle of incidence, i =? As δmin = 2i – A 36° = 2i – 60 i = 48°

Both deviation and dispersion. Hint: When a white light ray falls on the first surface of a prism, light rays of different colours due to their different speeds in glass get...
