Question

A ray is incident at an angle of incidence $i$ on one surface of a small angle prism (with angle of prism $A$ ) and emerges normally from the opposite surface. If the refractive index of the material of the prism is $μ$ , then the angle of incidence is nearly equal to:

Options:

Answer:

B

Solution:

$r_{2} = 0$

$r_{1} = A$

Apply Snell's law

$\sin i = μ \sin r_{1}$

for small angle $(r_{1} = A)$

$i = μ A$
