Electromagnetic radiation is propagating sinusoidal electric and magnetic fields. Are the peak amplitudes of these fields in any way related to the radiation's other parameters, e.g. its instensity?
Intensity is Power Flux Density, expressed in W/m2. The RMS amplitudes of the electric and magnetic fields are related to PFD in the following way, where R is the intrinsic impedance of the medium, 377 Ohms for free space:-jeremyfiennes said:Electromagnetic radiation is propagating sinusoidal electric and magnetic fields.

EM radiation amplitude refers to the strength or magnitude of an electromagnetic wave, which is a type of energy that travels through space in the form of waves.
Amplitude and intensity are directly related. The intensity of an electromagnetic wave is proportional to the square of its amplitude. This means that as the amplitude increases, the intensity also increases.
Yes, the peak of an EM wave is directly related to its intensity. The peak refers to the highest point of the wave, and the higher the peak, the greater the intensity of the wave.
The amplitude of EM radiation affects several properties of the wave, including its energy, frequency, and wavelength. Higher amplitude waves have more energy and shorter wavelengths, while lower amplitude waves have less energy and longer wavelengths.
The unit of measurement for EM radiation amplitude is volts per meter (V/m). This unit measures the strength of the electric field in the wave, which is directly related to the amplitude of the wave.
