Question

what is transverse wave and what is longitudinal wave​

Answer 1

Answer 2

Answer:

Transverse Waves : In this type of wave the particles of the medium vibrate in a  direction perpendicular to the direction of propogation of the wave. For example: waves produced in a stretched string.

Longtitudinal Waves :  These are the waves in which the particles of the medium vibrate along the direction of propogation of the wave. For example: sound wave.
