WebJul 21, 2024 · The amplitude of a wave will decrease if there is absorption of the wave's energy. This is true for any wave, E&M, sound, etc. I'm not sure what pictures you see on the internet related to this, but if the E&M wave is propagating through vacuum, then it's amplitude will not decrease. So what counts as absorption? WebIn electromagnetic waves, the amplitude is the maximum field strength of the electric and magnetic fields (Figure 16.10). The wave energy is determined by the wave amplitude. Figure 16.10 Energy carried by a wave depends on its amplitude. With electromagnetic waves, doubling the E fields and B fields quadruples the energy density u and the ...
