I've started a thread in usenet sci.physics.relativity

http://groups.google.co.uk/groups?h...9&seekm=SrSIc.48884$oh.46343@lakeread05#link4

but the answers given there didn't really satisfy me, so I'm back here.

I couldn't get people there to confirm that wavelength shortens as frequency increases when light source approaches lab frame, and that we could prove the change in wavelength by examining diffraction through a slit. Am I wrong? Why hesitate to confirm that wavelength shortens, I don't understand.

I'm thinking maybe wavelength has two components, one from electic and one from magnetic fields, and diffraction is due to the component perpendicular to light's direction, and the shortened wavelength is the other component. Wild guess, eh? I'm afraid to ask this on usenet.

On the other hand, I know that light isn't considered an electromagnetic wave anymore. There is wave/particle duality. I know light is considered as a probability wave and it collapses when detected, or something like that. But then, I'm confused, can we really talk about a wavelength associated with light or is it a leftover from the days of electromagnetic theory of light?

Now, you know I'm not the crackpot I used to be. But, this is theory development, and I'd like to throw in an idea. Instead of saying light explores all possible paths, maybe we could say a photon is a peak, and according to fourier transform, carries all possible frequencies. A single photon then can interact with itself after passing through two slits, because some of the frequency components would be filtered. Wavelength of light then would be the distance between two consecutive peaks (a single photon would not have a wavelength). Yeah, probably a stupid idea, and of course I haven't thought how to explain other light phenomena with this. And it is too simple so someone must have thought of it before. I'd appreciate if anyone knows a website that discusses this. Thanks.
