3.6 Frequency

Understand, and use the relationship between frequency and time period:

f = frequency (Hz) or (cycles/s)

T = Period (the time for one cycle) (s)

3.5 Wave speed

Understand the relationship between the speed, frequency and wavelength of a wave:

Wave speed = frequency x wavelength

or 

v = f x λ
