Problem 4DQ

The amplitude of a wave decreases gradually as the wave travels down a long, stretched string. What happens to the energy of the wave when this happens?

Step-by-Step Solution:

Solution to 4DQ Step 1 2 EA Step 2 As mentioned when a wave travels down a string, the amplitude decreases. Thus the energy of the wave also decreases. Consider A=A/2 2 Then EA /4, thus we see that when the amplitude is decreased by half, the energy of the wave is decreased by (¼) of the original value.
