Review

LAB 25 Motion of pulse

4.What does a specific point on a slinky do as a pulse goes by? Figure 2

6.What is observed when two similar pulses (same amplitude) are sent down the slinky, one from each end, oriented in the same direction, at the same time. Figure 5

7.When pulses are generated from each end, do they pass through or reflect back from each other? They pass through each other.

Figure 4 The superposition of two equal and opposite pulses on a coil spring. In the fifth picture they almost cancel each other.

When a pulse is sent from the end of a slinky, what is observed? Less Into More Dense Material

When a pulse is sent from the metal end of a slinky, what is observed? More Into Less Dense Material
