00:05Question says, the following phenomena cannot be observed for sound waves. A. Refraction
00:14B. Interference C. Diffraction D. Polarization
00:20is, sound waves can possess refraction, interference and also diffraction, but they cannot be polarized.
00:48So, the correct option will be depolarization. Because sound waves are longitudinal waves,
01:02so longitudinal waves cannot be polarized.
