Which of the following options regarding a longitudinal wave is false.
Open in App
Solution
The correct option is D Longitudinal wave can be polarized
Longitudinal waves possess all the characteristics of a wave. It has unique wavelength and velocity, and also transfer energy from one place to another.
In a Longitudinal wave , vibration of the particles of the medium is along the direction of propagation of wave.
For polarisation to occur, vibration of the particles of the medium should be perpendicular to the direction of propagation.
Hence, a Longitudinal wave cannot be polarised.
As, sound waves are a good example of longitudinal waves, Sound waves does not exibit polarisation.
