Calculate the angle ?. Answer in units of ? .
Homework Answers
Angle between incident ray and mirror 1 = 53
Angle between reflected ray and mirrir 1 = 53 ( i = r)
using angle sum property in triangle
Angle between incident ray and mirror = 180 - 53 - 53 = 74
deg
Angle between mirror 2 and reflected ray = 74 deg (i = r)
Angle between hortizontal and final ray = 53 - 74 = -21 deg
Angle between incident ray and horizontal = 53 deg
Net angle phi = 53 + 21 = 74 deg

Two plane mirrors are positioned so that the angle between the reflecting surfaces is θ = 100ᵒ. Light is incident on one of the mirrors with and angle of β = 40ᵒ relative to the normal to that mirror’s surface. The light goes from the first mirror surface to the second mirror surface. At what angle, relative to the normal to the second surface, does the light leave the second mirror surface? Show your work on a ray diagram.

How high from the floor is the spot on the wall?
A light ray strikes a plane mirror lying flat on a horizontal floor, making an angle of incidence = 61.8°. After reflecting from the mirror, the ray makes a spot on a vertical wall. The wall is a horizontal distance d=1.08 m from the point of reflection, as shown. How high from the floor is the spot on the wall? (Neglect the thickness of the mirror.)
