A prism has a refracting angle of 60?? When placed in the position of minimum deviation, it produces a deviation of 30?? The angle of incidence is

A vessel of depth 2d cm is half filled with a liquid of refractive index $\mu_{1}$ and the upper half with a liquid of refractive index$\mu_{2}$. The apparent depth of the vessel seen perpendicularly is

The refractive index for a prism is given as $\mu = \cot \frac{A}{2}$. Then, angle of minimum deviation in terms of angle of prism is

The communication using optical fibers is based on the principle of
