A beam of light is incident from air to water at an angle of 30o. Find the angle of refraction if the refractive index of water is 4/3
15o
18o
22o
24o
Correct answer is C
X = 43 r = ?
Shell’s law:. = Sini0Sinr0
= Sin300Sinr0
Sinr0 = 3Sin3004
Sin r0 = 0.375
R o = Sin-1 (0.375)
R o = 22.02 o
R o = 22 o
