If you "bow" a string on a violin you hear a note with a frequency of 1020 Hz. If the length of the string is about 40cm, what is the "wave" on the string? Draw a diagram to show the standing wave on the string.
Speed = frequency X wavelength
length is given ,so wavelength can be calculated by
wavelength = number of harmonics X length
