List of top Physics Questions on Refraction of Light asked in AIIMS

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

A prism is made up of material of refractive index $\sqrt{3}$. The angle of prism is $A$. If the angle of minimum deviation is equal to the angle of the prism, then the value of $A$ is

In optical fibre, the diameter of the core is kept small. This smaller diameter of the core ensures that the fibre should have incident angle more than the critical angle required for total internal reflection.

In refraction, light waves are bent on passing from one medium to the second medium, because, in the second medium:

The apparent depth of water in cylindrical water tank of diameter $2R\, cm$ is reducing at the rate of $x\, cm/$minute when water is being drained out at a constant rate. The amount of water drained in c.c. per minute is ($n_1$ = refractive index of air, $n_2$ = refractive index of water).

Sky appears to be blue in clear atmosphere due to light??

Relation between critical angle of water and the glass is

The rain drops are spherical in shape due to
