A ray of light suffers refraction through an equilateral prism. The deviation produced by the prism does not depend on the:

In a prism the ray of light suffers refraction at two faces. The prism produces a deviation at the first surface and another deviation at the second surface. Thus a...

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

Given, Angle of incidence, i = 48° Refracting angle, A = 60° Angle of minimum deviation, δmin =? As δmin = 2i – A δmin = 2(48) – 60 δmin = 36°

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

The deviation caused by a prism increases with the decrease in the wavelength of light incident on it.

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...

(i) Laws of refraction : (a) The incident ray, the normal and the refracted ray, all lie in the same plane. (b) The ratio of sine of the angle of incidence and...
