Two harmonic waves of the same frequency and phase but of different amplitudes move in opposite directions on a string.A periodic series of maxima and minima on the string are observed.What is the ratio of the maximum displacement at a minimum position to that at a maximum position,if one amplitude is 52% of the other? (This is called the standing wave ratio. )
A)0.32%
B)48%
C)0.0%
D)52%

The standing wave ratio is given by the ratio of the maximum displacement at a minimum position to that at a maximum position. In this case, one amplitude is 52% of the other, so the standing wave ratio is 0.52.
