GCSE Physics

Speed, Frequency & Wavelength

We can check the speed found using the length of the tank and the time taken:

speed = distance / time = 100 / 2 = 50 cm/s

So the relationship between speed, frequency and wavelength is:

wave speed = frequency x wavelength. v = f l.

Incidentally, the funny upside-down y is a greek letter called "lamda". You may need to know this formula!
