Please help my son year 12 physics -- frequency and wavelength

  1. Mar 4, 2015 #1
    my son is trying to find out how he can find an answer by being shown how to do the working out
    he wants to find out what the wavelength is if he only has the hz if he is 93.4 hz how does he find out what the wave lenth is

    Welcome to the PF, Martin.

    When you show your son how to use Google to find the relationship between wavelength and frequency, what do you find?

    BTW, that relationship will depend on the medium that the waves are propagating in. Sound in air has a different relationship versus light in air... :smile:

    You need to know the speed of the wave as well. (frequency*wavelength)=speed.
