Waves transfer enegry and information without transferring matter

Wavelength: The distance between a point on the cycle and the same point on the next cycle.(Measured in metres,m)

Amplitude: Maximum dispacement of a wave.(Measured in metres,m)

Frequency: Number of complete cycles produced or passing a point per second.(Measured in Hertz, Hz)

Time period: Time taken for one complete cycle to be produced or pass a point.

The wave equation

Word equation: wave speed= frequency x length

units m/s Hz m

Symbol equation: V=fλ

frequency=number of complete cycles

time taken
