Question

Difference between longitudinal and transverse wave

Answer 1

In a longitudial wave the particles do not move from one place to another but they simply oscillate back and forth about their position of rest. This is how sound wave propogate.
In a transverse wave particles do not oscillate along the the line of wave propogation but oscillate up and down about their mean position as the wave travels.This is how sound propogate. 

Answer 2

$\huge\colorbox{pink}{Transverse Wave : }$

(i) In transverse waves, the particles of the medium vibrates perpendicular to the direction of wave motion.

(ii) These waves travel in the form of alternate crest and troughs.

(iii) There waves can be transmitted through solids and surface of liquid.

(iv) They do not cause pressure changes in the medium through which they pass.

(v) Example :

a) Waves formed over water surface.

b) Waves on stretched string.

$\huge\colorbox{pink}{Longitudinal waves : }$

(i) In longitudinal waves, the particles of the medium. Vibrates along the direction of wave motion.

(ii) These waves travel in the form of alternate compression and rarefraction.

(iii) These waves can be transmitted through solids, liquid and gases.

(iv) They cause changes in the pressure of different parts of medium through which they can pass.

Example :

a) Sound waves in air.

b) Waves formed along compressed spring.
