Question

A ray of light traveling in air strike the water if angle 40 calculate refraction index of water if angle of reflaction is 29​

Answer 1

Answer:

Formula : u = sin i / sin r .( u = meu)

Given:

Angle of incidence = 40°.

Angle of refraction = 29°.

Solution :

u = sin i / sin r

u = sin 40° / sin 29°

u = 0.6428 / 0.4848

u = 1.32

Therefore, the refractive index of water is 1.3u.(meu).
