The figure shows three progressive waves A, B and c. wahat canbe concluded from the figure that with respect to wave A?

A

The wave C is ahead buy a phase angle of `pi//2` and the wave B lags behind by a phase `pi//2`

B

The wave C is lg behind by a phase angle of `pi//2` and the wave B is ahead by a phase angle `pi//2`

C

The wave C is ahead by a phase angle of pi and the wave B lags behind by a phase angle pi.

D

The wave C lags behind by a phase angle of pi and the wave B is ahead by a phase angle pi.

Text Solution

Verified by Experts

The correct Answer is:
b
In the figure, 'C' reaches the position where 'A' already reaches after `omegat =pi//2` and 'A' reaches the position where 'B' already reaches after `omega t=pi//2`.
