Light from a 504-nm monochromatic source is incident upon the surface of fused quartz (n = 1.56) at an angle of 17°. what is the angle of reflection (in degrees) from the surface?

73 degree

Explanation:

Angle of incidence = 17 degree

According to the laws of reflection, the angle of incidence is equal to the angle of reflection.

So, angle of reflection = 17 degree

Angle from the surface = 90 - 17 = 73 degree
