Question

Light is incident on a piece of glass in air at an angle of 44 degrees from the normal. If the index of refraction of the glass is 1.5, what is the angle in degrees that the refracted ray makes with the normal? ______ Round your answer to 1 decimal place.

Answer 1

Given data,

n₂ = 1.5

= 44^o

According to snell's law,

n₁ sin = n₂ sin

1 X sin44 = 1.5 X sin

0.694 = 1.5 X sin

sin = 0.462

= sin^-1(0.462)

= 27.51⁰
