MHT CET Physics question

Which of the following is NOT the characteristic of the progressive wave?

(A)All the vibrating particles of the medium have different amplitudes and frequencyCorrect
(B)State of oscillation changes from particle to particle
(C)For its propagation, medium has elasticity and inertia
(D)The form of wave repeats itself at equal intervals

Answer: (A)

Solution

In a progressive wave all particles have the same amplitude and frequency, so (a) is not a characteristic; the state of oscillation (phase)
