EM wave

  1. Dec 2, 2008 #1
    1. The problem statement, all variables and given/known
    Is it true that nothing can travel faster than the speed of light? Can't all electromagnetic waves travel at light speed. Also, if the speed of light is a constant, is the speed of the other electromagnetic waves a constant such as x rays, radio waves, and microwaves?

    2. Relevant equations

    E=hf C=fv

    3. The attempt at a solution
