hi guys please tell me about polarization... how can we use it to differentiate between longitudinal and transverse waves?
Answers
Answer:
In this case, the transverse polarization is associated with the direction of the shear stress and displacement in directions perpendicular to the propagation direction, while the longitudinal polarization describes compression of the solid and vibration along the direction of propagation.
Explanation:
With transverse waves, there is a choice in which direction (in which plane) the oscillations occur. For instance, let the transverse wave move in z
-direction. Then the oscillations could be for instance in the x−z-plane, or they could be in the y−z
-plane or they could be anywhere in between. In order to distinguish between these different waves (i.e. waves with oscillations in different directions), physicists introduce a parameter called "polarization" which describes the geometrical orientation of oscillations.
With longitudinal waves on the other hand, the oscillations always occur in only one direction, namely along the wave. There is no need to distinguish different oscillations direction, because there is only one oscillation direction. Therefore it does not make much sense to speak of "polarization" of longitudinal waves, because those waves are fully described by wavelength/frequency/velocity.

Answer:
Hey!
——————————————-
Polarization, property of certain electromagnetic radiations in which the direction and magnitude of the vibrating electric field are related in a specified way.
Polarization (also polarisation) is a property applying to transverse waves that specifies the geometrical orientation of the oscillations. In a transverse wave, the direction of the oscillation is perpendicular to the direction of motion of the wave.
Difference:
Transverse Waves: Displacement of the medium is perpendicular to the direction of propagation of the wave.
eg. Electromagnetic radiation
Longitudinal Waves: Displacement of the medium is parallel to the direction of propagation of the wave.
eg. Sound waves
