Snell's law of refraction states that

n_i/n_r = sin _r/ sin _i

Here n_i is the refractive index of the incident medium and n_r is the refractive index of refracting medium. Also _i is the incident angle and _r is the angle of refraction.

Now here

a) the refractive index of fluorite is 1.434 and that of the air is 1. Here given that _i = 45⁰

Therefore 1/0.434 = sin _r/sin 45

Sin_r = sin₂ = 0.697*0.707 = 0.493

Therefore ₂ = sin^-1 0. 493

₂ = 29.54⁰

b) the refractive index of crown glass is 1.52

Therefore 1/1.52 = sin₂/ sin 45

sin₂ = 0.658*0.707 = 0.465

Therefore ₂ = 27.71⁰

c) the refractive index of carbon tetra chloride is 1.461

Therefore 1/1.461 = sin₂/sin 45

sin₂ = 0.684*0.707 = 0.483

₂ = 28.88⁰
