Light is considered a transverse wave, but its oscillations are not of the medium particles or their pressure or density—it is not a mechanical wave.

In longitudinal waves, particles move parallel to the wave’s direction, while in transverse waves, particles move perpendicular to the wave’s direction.

When a pebble is dropped in a pond, the waves observed on the water surface are an example of transverse waves.

In a transverse wave, particles of the medium oscillate up and down about their mean positions, perpendicular to the direction of wave propagation, whereas in a longitudinal wave, particles oscillate parallel to the direction of propagation.

No, in longitudinal waves, particles of the medium do not move from one place to another; they simply oscillate back and forth about their position of rest.

Sound waves are classified as longitudinal waves because the individual particles of the medium oscillate back and forth in a direction parallel to the direction of sound propagation.

Rarefactions (R) are the regions where the coils of a slinky are further apart.

In longitudinal waves, particles of the medium move in a direction parallel to the direction of propagation of the disturbance.

The regions where the coils become closer are called compressions (C).

The movement of vibrating objects creates pressure variations in the medium, leading to the propagation of sound waves.
