The wavelength (λ) of a wave is the distance ... work out the frequency of a wave from a displacement-time graph – remember the frequency is the number of waves per second.

The resulting data and graph are shown below. The frequency is derived from the data using this formula: frequency = 300,000,000 m/s / (2 * half-wavelength measurement) The half-wavelength ...

Figure caption, This displacement-distance graph is how you would measure a wavelength of a wave Frequency – the number of complete vibrations in one second. This is the same as the number of ...
