I need to understand the relationship between the three. When does the wavelength stay the same as there is a change in one of the other two variables? When does it change as there is a change in one of the other variables? My understanding is this: If the speed changes due to a shift in the medium, let's say increases, only frequency increases.
But if the frequency changes due to a change in the source of vibrations, wavelength would change to compensate for it, since there is no change in medium, correct?
I just need to know if this is right, because I am not sure if I am getting it, and if there is anything about this relationship that I am missing. Thank you:)
