In Fig., determine the apparent shift in the position of the coin. Also, find the effective refractive index of the combinatino of the glass and water slab.

A beaker contains water up to a height h_1 and K oil above water up to another height h_2. Find the apparent shift in the position of the bottom of the beaker when viewed from above. Refractive index of water is mu_1 and that of K.oil is mu_2 .

Considering normal incidence of ray, the equivalent refractive index of combination of two slabs shown in Fig. is. .

If the refractive index of a certain glass with respect to water is 1.25 , find the refractive index of water with respect to the glass.

Which has higher refractive index: water or glass?

Find the refractive index of water with respect to glass if the refractive index of water is 4/3 and the refractive index of glass is 3/2.

If the absolute refractive index of glass is 1.5 and that of water is (4)/(3) , find the refractive index of water with respect to glass.
