polarised
|
|
|
transverse
|
|
|
longitudinal
|
|
|
electromagnetic

Explanation:
Detailed explanation-1: -Sound wave is called longitudinal wave because it is produced by compressions and rarefactions in the air. The air particles vibrate parallel to the direction of propagation.
Detailed explanation-2: -Sound waves are not transverse waves because their oscillations are parallel to the direction of the energy transport.
Detailed explanation-3: -Hence, the sound waves in the air are longitudinal waves.
Detailed explanation-4: -All electromagnetic waves (light waves, microwaves, X-rays, radio waves) are transverse. All sound waves are longitudinal.
