Question

The refractive index of alcohol is 1.36. calculate the value of critical angle for alcohol with respect to air?​

Answer 1

Answer:

What will be value of the refractive index of alcohol with respect to carbon disulphide? The refractive index of alcohol with respect to air is 1.36 and that of carbon disulphide with respect to air is 1.63.

Let's assume that by "air" we mean "vacuum" and the speed of light in air is equal to the speed of light in vacuum (almost true).

And the speed of light in air, v, in water is vw and in carbon disulphide is vc.

Thus the refractive indexes n are

Then the relative refractive index of water to carbon disulphide, nwc, (light from water into carbon disulphide), will be:
