Question

Explain– wave motion is doubly periodic

Answer 1

Answer:

Explanation:

When waves are propagated through a medium, the form of the waves repeats after equal intervals of time - wave motion is periodic in time. The form of the waves keeps repeating at equal distance - wave motion is periodic in space.

Answer 2

Answer:

Wave motion is both periodic in space and periodic in time. Hence it is a doubly periodic phenomenon. ... The wave travels from one medium to another, the wave speed and wavelength change but the frequency remains the same because the frequency is determined by the source.
