Radiowaves to light

  1. Mar 22, 2010 #1
    If a rocket is flying towards a radio transmitter that emits radiowaves (100 fm for instance) fast enough. does these radio waves get stacked up and become visible light.

    extrapolated question. can we (by changing the relative velocities between transmiter and receiver) shift from any wavelength to any wavelength?

    Yes. Standard Doppler Shifting.

    And while that is going on you measure increasing energy of the waves as well....

    Hmmm... it sounds like the N-Wave in trans-sonic flight! Of course, there is no trans-c flight, and I guess ńĆerenkov Rad is that "boom", short of an FTL miracle/catastrophe.
