Question

Is Huygen's principle valid for Longitudinal sound waves??

Answer 1

Explanation:

Longitudinal sound waves are monochromatic or monotone in nature.

Also, Longitudinal wave propagates in space same as Light waves having a spherical symmetry like structure travelling with the same velocity in a homogenous medium which gives us enough evidence that Huygens’s principle is also applicable to sound waves.

pls follow me.

Answer 2

S it is is valid for longitudinal waves but except some things which are states. He tells that it will be nit explained fir photo electric effects,black board effect , comptons effect extra
