Why cant sound waves be plane polarised?

Answer 1

Because transverse waves like electromagnetic waves (light) move side to side when the travel, and we can limit the side-to-side motion of a wave, and still allow the wave to pass. In longitudinal waves, we cannot limit longitudinal motion without actually "blocking" the wave.

Picture two transverse waves that are moving in the same direction. One is moving up and down as it travels and the other is moving side to side. We can install a barrier of vertical slits in the path of the waves. The vertical slits will accommodate the wave that moves up and down. The other wave will be trying to move from side to side when it impinges on the barrier, and it will be "blocked" there. The vertical slits polarize the wave.

With longitudinal waves, there is no equivalent "filter" or barrier we can use to polarize the wave.

Answer 2

Sound waves are longitudinal waves, meaning the vibrations occur along the direction of wave propagation. Unlike transverse waves, such as light waves, the oscillations in sound waves cannot be restricted to a single plane to achieve polarization. This is because the particles in the medium vibrate back and forth in the same direction as the wave motion, making it impossible to selectively filter out vibrations to achieve polarization.

Answer 3

Sound waves are easier to make. You can just talk and get sound waves while the light waves are more dense and take up more time.

Answer 4

Because sound waves do not travel in a straight line. { *§tåíñlè$$}

Answer 5

of it depend upon the non mechanical waves and the mechanical waves. sound waves are paralell to the motion of the sound it is longitudinal while light waves are transverse

Answer 6

Light has Transverse waves and sound does not.
