Question

Sound waves do not exhibit polarization because, unlike light waves, they are not:

• A. longitudinal
• B. coherent
• C. dispersive
• D. transverse
• E. refractive

Answer 1

Answer: (D)

transverse

In polarization the vibrations of electric vector of light are restricted by a polariser in a single plane because vibrations are perpendicular to the propagation of light , as light is a transverse wave .

Polarization is the phenomenon of transverse waves only , it does not happen in longitudinal waves , as sound waves are longitudinal waves in which vibrations are in the direction of propagation of wave so they pass the polariser without any change and doesn't experience any polarization .
