Question

Which among x-rays,sound waves and radio waves can be polarized

Answer 1

answer : x - rays and radio waves can be polarized.

explanation : polarisation means that we filter the wave and we only select the part of the wave that oscillates in a specific direction.

here, x - rays and radio waves are transverse waves. as we know, in transverse wave, particle oscillates perpendicular to direction of motion of wave. note that there are more than one direction perpendicular to direction of motion. so, it can be polarized.

while sound wave is longitudinal wave. it can't be polarized as oscillation of the wave is always in the direction of propagation.

[ note : only transverse wave can be polarized. ]
