Electro-magnetic Radiation and Cresting Amplitude

  1. Dec 24, 2011 #1
    In electro-magnetic radiation is the cresting amplitude proportionate to the wavelength; or is it the same for all wavelengths, or is it a variable?

    The amplitude is variable, and independent of the wavelength. It's related to how much power the wave carries, and for visible light it's related to the brightness of the light.
