Calculate wavelength from wave speed and frequency.

Wavelength is found by rearranging v = f? to ? = v/f, then dividing wave speed by frequency. For example, 12 m/s divided by 4 Hz gives a wavelength of 3 m. The answer must be a distance unit, usually metres, because wavelength is the distance between matching points such as crest to crest. This objective is not asking for amplitude, period or frequency; it is using speed and frequency to find spacing along the wave. Within the subtopic Properties of waves in Waves in air, fluids and solids, the explanation is anchored to wavelength, frequency, wave speed and uses those terms in the approved AQA GCSE Physics Waves context.
