Waves transfer energy and information without transferring matter.
Wave length: the distance between a point on one cycle and the same point on the next cycle.Measured in metres,m.
Amplitude: maximum displacement of a wave.Measured in metres,m.
Frequency: nuber of complete cycles produced or passing a point per second. Measured in Hertz,Hz.
Time period: The time taken for 1 complete cycle to be produced or pass a point.
Wave speed= frequency x wavelength
m/s hz x m
frequency=number of complete cycles time taken
