Answer:

2.301

Explanation:

Given, the ray of light strikes the surface of water at an angle of 30°. So, the angle between normal and incident ray will be 60°. Now, refractive index of water = sine of angle of incidence/ sine of angle of refraction. n= sine 60°/ sine 22.1°=0.866/0.3762(sine 60° =0.866 and sine 22.1° =0.3762) =2.30197.
