Two waves of equal frequency f and veloc...

Two waves of equal frequency `f` and velocity `v` travel in opposite directions along the same path. The waves have amplitudes `A` and `3 A` . Then:

A

the amplitude of the resulting wave varies with position between maxima of amplitude `4A` and minima of zero amplitude

B

the distance between a maxima and adjacent minima of amplitude is `(v)/(2f)`

C

at a point on the path the average displacement is zero `rArr` Average displacement of medium particle of any point is zero.

D

the position of a maxima or minima of amplitude does not change with time
