Answer:
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°.
