Amplitude of all electromagnetic wave are same ?

  1. Feb 21, 2013 #1
    Gamma ray can use to kill tumour because of higher frequency and therefore higher energy.
    The energy here is the number of time of the wave hit on the tumor or the amplitude of wave ?

    Thank you.

    It's not the amplitude of the wave (number of photons) but the frequency (photon type) that plays a role here.
