what is the difference between transverse wave and longitudinal wave?

transverse wave is a wave in which the particles in the medium vibrate perpendicularly tothe direction of the propagation of the wave

Longitudinal wave is a wave in which the particles vibrate paralell to the direction of the propagation of the wave

Transverse wave have crust trough

Longitudinal wave have compressed and rarefied regions

Transverse wave requires no medium

Longitudinal wave requires medium

Example of transverse wave : waves formed on the surface of the water

:light waves

Example of Longitudinal wave : waves formed inside of the water

: sound waves
