MHT CET 2022 Physics question

In a stationary wave all particles

(A)vibrate in S.H.M. of different periods and different amplitudes
(B)vibrate in S.H.M. of same period and amplitudes
(C)except at nodes vibrate in S.H.M. of same period but of different amplitudesCorrect
(D)except at nodes vibrate in S.H.M. of same period and same amplitude

Answer: (C)

Solution

A stationary wave is . Every particle oscillates with the same angular frequency (same period), but the amplitude depends on the position : it is zero at nodes (particles do not vibrate) and maximum
