PhysicsEasysingle choice

A ray of light is incident at an angle ' $i$ ' on one face of prism of small angle 'A' and emerges normally from the other surface. ' $μ$ ' is the refractive index of the material of the prism. The angle of incidence is

Options:

Answer:

Solution:

For small angled prism $δ_{m} = (μ - 1) A$ Again $i + e = A + δ_{m} = μ A - A$ Here $e = 0 ∴ i = A + δ_{m} = A + μ A - A = μ A$
