11yes, but how ?
Ques 1) Figure (a)
Three progressive waves A,B and C are shown in the figure. With respect to wave A, the wave C
(a) lags behind the phase by \pi /2 and B leads by \pi /2
(b) leads in phase by \pi /2 and B lags behind by \pi /2
(c) leads in phase by \pi and B lags behind by \pi
(d) lags behind in phase by \pi and B leads by \pi
Ques 2) Figure (b)
The figure represent two snaps of a travelling wave on a string of mass per unit length \mu = 0.25 kg/m. The first snap is taken at t=0 and the second is taken at t = 0.05 sec. Determine the speed of the wave.

1At origin the phase of curve 'c' w.r.t A is -pi/2 and that of B is + pi/2
