Question
Is Huygen’s principle valid for longitudinal sound waves?
Solution
Yes, it can Huygen’s principle basically states that every point wavefront can be considered as a secondary source of tiny wavelets that spread out in the forward direction of the wave itself. The disturbance due to the source propagates in spherical symmetry that is in all directions. The formation of the wavefront is in accordance with Huygen’s principle.
So, Huygen’s principle is valid for longitudinal sound waves also.
