PhysicsEasysingle choice

A ray of light is incident at an angle of incidence, $i$ , on one face of a prism of angle $A$ (assumed to be small) and emerges normally from the opposite face. If the refractive index of the prism is $μ$ , the angle of incidence $i$ , is nearly equal to

Options:

Answer:

Solution:

Refractive index $μ = \frac{sin i}{sin r} μ = \frac{sin i}{sin A}$ In case of small angle. $μ i = \frac{i}{A} = μ A$
