WHAT ARE LONGITUDINAL AND TRANSVERSE WAVES

Longitudinal and transverse waves

 LONGITUDINAL WAVES :  If the direction of the wave and its constituent particles is same i.e they are alligned in same direction then the wave is known as longitudinal wave .

TRANSVERSE WAVE :  If the direction of wave and its constituent particles is perpendicular to each  other  ,then the wave is known as transverse wave .

Sound is transmitted through gases, plasma, and liquids as longitudinal waves, also called compression waves. Through solids, however, it can be transmitted as both longitudinal waves and transverse waves. Longitudinal sound waves are waves of alternating pressure deviations from the equilibrium pressure, causing local regions of compression and rarefaction, while transverse waves (in solids) are waves of alternating shear stress at right angle to the direction of propagation. Additionally, sound waves may be viewed simply by parabolic mirrors and objects that produce sound.
The energy carried by an oscillating sound wave converts back and forth between the potential energy of the extra compression (in case of longitudinal waves) or lateral displacement strain (in case of transverse waves) of the matter, and the kinetic energy of the displacement velocity of particles of the medium.
