| 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 |
