By convention, that's said to be the direction of the E field.
Longitudinal waves are characterized by particles oscillating in the same direction as the wave's propagation. They do not display polarization because the oscillations are along the same axis. However, longitudinal waves can diffract as they bend around obstacles or spread out upon encountering an aperture.
The phenomenon that sound wave fails to exhibit is polarization.
polarization
A polarization experiment demonstrates that light is a transverse wave composed of oscillating electric and magnetic fields perpendicular to the direction of propagation. It also shows that light waves are polarized, meaning the electric field oscillates in a specific orientation. This experiment helps to study the wave nature of light and confirm the wave theory of light propagation.
Polarization and Interference confirm light is a wave.
Here is Wikipedias definition:In electrodynamics, circular polarization of an electromagnetic wave is a polarization where the tip of the electric field vector, at a fixed point in space, describes a circle as time progresses. If the wave is frozen in time the electric field vectors describe a helix along the direction of propagation. Circular polarization is a limiting case of the more general condition of elliptical polarization.
Relaxed
That is correct. Polarization is possible only when the direction of vibration is perpendicular to the direction of the wave travel, such is in light. In sound waves, the direction of vibration (compression) is the same direction as the direction of the travel of the sound wave, and therefore polarization is not possible.
No, electromagnetic (EM) waves are different from sound waves. EM waves are vibrations of electric and magnetic fields that do not need a medium to travel through, while sound waves are mechanical vibrations that require a medium, such as air or water, to propagate.
polarization of wave means to allow in one particular direction either it may be a horizontal or vertical and block other direction
em wave is generated by photons which emitter the energy in the form of light
