Solution
Polarization
Explanation:
The property of the wave that confines its orientations to one specific direction is called polarization.
For a transverse wave, the direction of motion is perpendicular to the direction in which the oscillation occurs. But as for longitudinal waves, both these motions are in the same direction. So there is no scope for confinement. That is, there is no such phenomenon of polarization for longitudinal waves. Light waves undergo polarization. This behaviour further implies that the light is a transverse wave.
