Interference

How does the amplitude of a wave change when it encounters another wave? When multiple waves exist in the same place at the same time, interference occurs. Wave interference can be either constructive or destructive, causing the amplitude of the resultant wave to be different than the individual waves. In this investigation you will observe the interaction of wave pulses on a spring and draw a conclusion about when constructive and destructive interference occur in waves.
