1. $\frac{\mathrm{\pi}}{4}$

2. ${\mathrm{sin}}^{-1}\left(\frac{3}{4}\right)$

3. $\frac{1}{2}{\mathrm{sin}}^{-1}\left(\frac{3}{4}\right)$

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 $\mu $, the angle of incidence i is nearly equal to:

1. | \(\mu \mathrm{A} \) | 2. | \(\frac{\mu A}{2} \) |

3. | \(A / \mu \) | 4. | \(A / 2 \mu\) |
