(a) What would the scale reading be if the container in Figure \(13.22 b\) were traveling at constant speed instead of accelerating?

(b) Describe the path of the light pulse in the reference frame of the elevator in Figure 13.24 b if the elevator were traveling at constant speed.

Figure 13.24 A light pulse traverses an accelerating container. (a) Earth reference frame light pulse Elevator floor accelerates upward toward light pulse. (b) Reference frame of elevator Pulse behaves as though falling in response to gravity.
