a) How rapidly does the distance between you and your mirror image decrease if you walk directly toward a mirror with a speed of 3.1 m/s? b) Repeat part A for the case in which you walk toward a mirror but at an angle of 26∘ to its normal.

The mirror in the figure (Figure 1)deflects a horizontal laser beam by angle θ. What is the angle ϕ if θ = 62 ∘.

A mirror is rotating, reflecting the incident rays. The angular speed of the reflected ray is wB. VWhat is the angular speed of the rotating mirror, WM? 2WB WB 0.5wB

A ball is dropped from rest 3.00 m directly above the vertex of a concave mirror having a radius of 1.00 m and lying in a horizontal plane. (a) Describe the motion of the ball’s image in the mirror. (b) At what time do the ball and its image coincide?

Two plane mirrors make the angle a = 58.0° between them. A ray of light incident on one of the mirrors is reflected and it hits the second mirror, as shown in the figure. Determine the angle ẞ between the ray incident on the first mirror and the ray reflected off of the second mirror. B = B
