A lamp is twice as far in front of a plane mirror as a person is. Light from the lamp reaches the person via two paths. It strikes the mirror at a 36.1° angle of incidence and reflects from it before reaching the person. The total time for the light to travel this path includes the time to travel to the mirror and the time to travel from the mirror to the person. The light also travels directly to the person without reflecting. Find the ratio of the total travel time along the reflected path to the travel time along the direct path.

A small ball is held at a point—A, B, or C—in front of a plane mirror, as shown in (Figure 2) . Rank points A, B, and C according to the distance between the actual ball and the image of the ball, from greatest to smallest. If any two ball locations produce the same distance between the ball and its image, overlap the location points.

A plane mirror rotates about a vertical axis in its plane at 35 revs s^-1 and reflects a narrow beam of light to a stationary mirror 200 m away. This mirror reflects the light normally so that it is again reflected from the rotating mirror. The light now makes an angle of 2.0 minutes with the path it would travel if both mirrors were stationary. Calculate the velocity of light. Please can you explain the solution to this question step...
