EM waves stand for Electromagnetic waves.
The wavelength of an electromagnetic (EM) wave is inversely proportional to its energy - shorter wavelengths correspond to higher energy, and longer wavelengths correspond to lower energy. This phenomenon is described by the equation E = hν, where E is the energy of the EM wave, h is Planck's constant, and ν is the frequency of the wave.
The higher the frequency of a wave, the higher its energy.
By convention, that's said to be the direction of the E field.
The shorter the wavelength of a wave, the higher its energy.
EM waves stand for Electromagnetic waves.
E=hv Where: E is energy h is plank's constant and v is frequency.
em wave is generated by photons which emitter the energy in the form of light
The frequency of an electromagnetic (EM) wave is directly proportional to its energy. This means that as the frequency of the EM wave increases, so does its energy. Conversely, a decrease in frequency leads to a decrease in energy of the EM wave.

I think Non linear absorption means when EM wave is absorbed by some absorber and polarisation of that absorber is higher order dependent on susceptibility and electric field. P = x(1)E + x(2) E2 + x(3) E3..... x is susceptibility and E is electric field of EM wave.
