Measuring waves on a string

To find standing wave frequencies, increase the frequency of the oscillator until a standing wave pattern is seen. The wavelength of the waves can be found from the length of the oscillating string and the standing wave pattern The speed of waves on a string only depends on the properties of the wave medium (the string). For waves on a string, frequency and wavelength are inversely proportional Control variables are the quantities that must be kept the same during experiments so they don’t affect results.
