Light waves that vibrate in only one plane are called polarized.
One clear indication is that light can be polarized. By their nature, longitudinal waves can't be polarized.
Transverse waves can be plane-polarized; longitudinal waves can not be.
Polarized waves.
Sound wave is a mechanical wave. It means that, for propagation, it badly needs a material medium. But, light waves are not mechanical waves. They are electromagnetic waves. It does not need a material medium. It can pass even through vacuum. Sound wave is longitudinal in nature where as light waves are transverse in nature. Being transverse, light can be polarized. But, sound waves being longitudinal cannot be polarized.
No. Only transverse waves can be polarized Ultrasonic wasves are sound waves, therefore are longitudinal.
Polarized light waves
The very question is wrong. Sound waves being longitudinal cannot be polarized. Electromagnetic wave being transverse can be polarized

P polarized waves have electric field the plane of incedence while S polarized waves have electric field which is perpendicular to the plane of incidence
Transverse waves can be plane-polarized; longitudinal waves can not be.
Polarized waves.
For polarization the direction of the oscillation has to be perpendicular to the direction of travel. In sound waves, which are longitudinal waves, this isn't the case and thereby can not be polarized.

No. Since longitudinal waves are vibrating in the direction that they are traveling, polarization has no meaning in their case.
