When light is incident from air to crown glass, the angle of incidence is 24.00°. what is the angle of refraction? note that the refractive index of air is 1.00 and that of crown glass is 1.52.

The angle of refraction in the crown glass is 15.5°.

Step-by-step explanation:

known values

angle of incidence (θ1) = 24.00

refractive index of air (n1) = 1.00

refractive index of crown glass (n2) = 1.52

unknown value: angle of refraction (θ2)

Snell’s law equation: n1 sin θ1 = n2 sin θ2

Substitute known values in this equation to get

(1)(sin 24°) = (1.52)(sin θ2)

sin θr = 0.27

θr = 15.5°

The angle of refraction in the crown glass is 15.5°.
