Hi,

I am writing up an investigation about the acoustic Doppler Effect, with the source moving towards the reciever. From my equations I understand that the change in frequency is proportional to the original source frequency. However i don't know how to explain this in terms of what actually happens to the waves. I understand how the Doppler Effect causes an increase in percieved frequency, but why would having a higher original frequency increase the change in frequency i.e. the frequency shift? Anyone?

Thanx
