Chapter 14: Wave Motion We now leave our studies of mechanics and take up the second major topic of the course – wave motion (though it is similar to SHM) Wave – a traveling disturbance which carries energy from one point to another, but without the translation of mass A wave usually travels through a medium (gas, liquid, solid), except for light (an electromagnetic wave) which can propagate through a vacuum Wave pulse

The particles of the medium which convey the wave, can be said to oscillate about their equilibrium positions (like SHM) Waves can be classified according to the direction of the oscillatory displacement Transverse waves – the displacement (of the particle conveying the wave) is perpendicular to the direction of the wave; examples are a guitar string and light Longitudinal waves – the displacement is along the direction of the wave; examples are sound, the spring, and seismic waves

Some waves can be a mixture of longitudinal and transverse modes – surface water wave
