like when the wavelength shortens when the particle goes faster, would, from a stationary reference point relative to the particle's motion, because of the motion, the wavelength appear to be even shorter?

I don't think this would ever come up on any of my tests in high school, but how would one answer a question combining the Broglie Wavelength of a particle and Special relativity? Are they cumulative? BW : λ= h/mv

just read the sub faq for relativity, apparently if I look at a photon's rest frame everything I derive from it is meaningless :P ah well...

but is that really a Lorentz contraction or is that just gravity messing with space time? or is it essentially the same? :P

I see what you mean by "changing energy" and that makes sense :) Once they start from a source they stay at a constant intrinsic energy level until annihilation, or wherever they end up. Changing the energy after the creation of photons wasn't exactly my idea, but I'm glad that you sorted that...

I was under the assumption that photons were able to have different energy levels where E=hf, and then for the photoelectric effect you can measure the energy through E=W+kE of the ejected electron. And yeah the Doppler effect would do the red and blue shifts :)

or actually, is there a model that explains this? I haven't really looked in depth yet, but if there is that would be helpful if someone could link to it :)

I'm in agreement with Drakkith, length contraction would depend on how fast you lowered the rope. The black hole would manipulate space-time, but I don't think it's the same thing...

I'm not suggesting that some light is traveling faster than other light. Obviously light's speed is constant (in vacuum). I can see how you might need a round trip to emphasize the "relativityness" of the idea, but the idea is more about what happens after you reach the speed limit and add more...

In high school, doing modern physics, and was struck by a thought about light, energy of a photon and the "speed limit" of relativity. I'm probably very wrong, but I would like to be shown why :) My understanding of energy and matter relations is that when you increase the energy levels...
