What is the Height of EM Radiation

  1. Mar 12, 2013 #1
    Hello,
    I have always wondered, what the relation of wavelength and frequency to the amplitude is.
    Is there an equation? Does it vary with different types of waves? Can it change?

    There is none. They are independent quantities. (Frequency and wavelength are of course related by the wave speed.)

    Amplitude is often graphically expressed as displacement (or height re: thread title). This is just a graphical convenience, obviously in reality amplitude and displacement are different things as they possess different units.

    Light does not actually 'wiggle from side to side'. That picture is responsible for a lot of misconceptions about EM.
