Question

Ina plane progressive harmonic wave ,particle speed is always less than the wave speed,if ?

Answer 1

Explanation:

Plane progressive harmonic wave is a wave in which wave travels in same direction without any change in the amplitude and the frequency.

The particles vibrate with the simple harmonic motion about their mean position. Wave is a disturbance which is carried away from one particle to the another particle.

Therefore, the speed of the particle is always less than the wave speed.
