l T-Mobile LTE 7:40 PM a blackboard.kean.edu 47% QUESTION Air Glass A light ray travels from glass to air at an angle of incidence 81- 35°. The ray partially reflected from the glass-air boundary at the angle 82 and partially refracted at the angle 83. The index of refraction of the glass is 1.6. At what amgle of incidence will no light enter the air? An Object n air is placed 10 cm in front of a refracting surface whose index of refraction is 1.5 and whose radius of curvature is 20. Find the image distance.

Explanation / Answer

1.

Using snell's law:

n1*sin A1 = n2*sin A2

n1 = refractive index of glass = 1.6

n2 = refractive index of air = 1.0

A1 = Angle of incidence = 35 deg

A2 = angle of refraction = ?

sin A2 = (n1/n2)*sin A1

A2 = arcsin ((n1/n2)*sin A1)

Using given values:

A2 = arcsin ((1.6/1.0)*sin 35 deg)

A2 = 66.6 deg

Correct option is D.
