The critical angle for a certain air-liquid surface is 47.7°. what is the index of refraction of the liquid? round to the nearest hundredth. nair = 1.00 answer

The index of refraction of the liquid is 1.35.

Explanation:

It is given that,

Critical angle for a certain air-liquid surface,

Let n₁ is the refractive index of liquid and n₂ is the refractive index of air, n₂ =1

Using Snell's law for air liquid interface as :

So, the index of refraction of the liquid is 1.35. Hence, this is the required solution.
