I have a few questions concerning the Doppler Effect, I know what it is in terms of a moving object, and how speed effects fequency etc. but I'm more interested in the explantions. My actual knowledge of the two explanations is reasonably vague.
The one I am interested in is the compression of the sound waves being emitted by say for example a train, for the people that it is approaching they will hear a high pitch, and people below a lower pitch. Can anyone expand on this idea, and possibly explain it a bit more if necessary. I've heard people talking about compression of the waves?
I have been told that there are two formulas for the Doppler effect, one a simpler one and the other a more complex one. I think the simpler one is [tex]v = f \lambda[/tex], this is useful in that it illistrates that if v remains constant ie. the speed of sound around 320m/s and the wave frequency increases, then the wavelength must decrease.
I don't know of a more complex one, but is there one that would take more factors into account? I don't seem to be able to find it, I would have thought it would have taken into account distance aswell? Any ideas?
Thank you, any help would be great
