Waves

Question	Answer
Define waves - medium to travel - disturbance - particles - energy	transfer or flow of energy from one point to another without transfer of particles/matter. It is formed by a wave of disturbance that travels. It may or may not need a medium
Define transverse and longitudinal wave with an example	Transverse wave - oscillate back and forth about their own equilibrium. Doesn't need a medium eg : light waves Longitudinal wave - Particles move up and down. waves move perpendicular to particle motion. Needs a medium to travel eg: sound waves
Definition of amplitude and wavelength	Amplitude - distance from center line to top of crest or to bottom of trough Wavelength - horizontal distance between 2 adjacent crests. measure in meter. symbol - lambda
Formula of speed of a wave	v = f x lambda
Definition of damping	reduction in amplitude of an oscillation as a result of energy being drained from the system
How to calculate wave speed	wave speed = wavelength x frequency
Intensity of wave	Rate at which energy transfers across an area. rate of energy flow per unit area
a sound is that characteristic which distinguishes between 2 sounds	Quality/Timbre
