There are many examples of waves: - Seismic waves - Ripples on a pond - Sound - Electromagnetic wave including light Waves A wave can have a short duration – just a quick pulse; these are called “wave pulses” A transverse wave is a wave in which the oscillations are transverse to the direction the wave travels A longitudinal wave is a wave in which the oscillations are along the direction the wave travels A wave can also repeat; these are called continuous waves Types of Waves ) cos( ) , ( kx t A t x y

Wavelength and Speed of Waves The “speed” of a wave is the rate of movement of the disturbance. It is not the speed of the individual particles! The speed is determined by the properties of the medium f T v / λ - wave length T - period f - frequency t y T x y λ ) cos( ) , ( kx t A t x y Sinusoidal waves  / 2 / 2 k T k T v / /
