The intensity of an electromagnetic wave is given by the following equation:
I = (ε0c/2)E02, where ε0 is the permittivity of free space, c is the speed of light in a vacuum, and E0 is the maximum amplitude of the electric field.
I added a related link below that shows how to derive this.

What is the amplitude of a sound wave a measure of?
The amplitude of a sound wave is a measure of the maximum displacement of particles in the medium from their resting position. It represents the loudness or intensity of the sound wave.
How do you measure of amplitude for electromagnetic waves?
The amplitude of an electromagnetic wave is measured by the maximum displacement of the electric or magnetic fields from their equilibrium position. It represents the strength or intensity of the wave and is typically measured in volts per meter for electric fields and teslas for magnetic fields.
Do electromagnetic waves have amplitude?
Yes, electromagnetic waves have amplitude, which refers to the maximum value of the electric or magnetic field in the wave. The amplitude determines the intensity or strength of the wave.
What is the amplitude of a wave is a direct measure of what?
The amplitude of a wave is a direct measure of the energy or intensity of the wave. It represents the maximum displacement of a particle from its equilibrium position as the wave passes through a medium. Larger amplitudes indicate greater energy or intensity of the wave.
What equation is used to measure wave speed?
The equation used to measure wave speed is: Wave speed = frequency x wavelength
Is there a scale used to measure the intensity of a heat wave?
is there a scale used to measure the intensity of heat wave
How are the different types of electromagnetic wave organized?
By frequency on the electromagnetic spectrum

What equation is used to measure wave speed?
The equation used to measure wave speed is: Wave speed = frequency x wavelength
The measure of a waves intensity?
The intensity of a wave is usually measured as the power transmitted through a unit area perpendicular to the direction of wave propagation. It is usually expressed in watts per square meter (W/m^2) and is proportional to the square of the amplitude of the wave. Stronger waves have higher intensity levels.
What happens when you increase electromagnetic wave?
Increasing the intensity of an electromagnetic wave will result in higher energy and amplitude of the wave, which can lead to increased potential for heating, radiation exposure, and potential health risks. Additionally, at very high intensities, electromagnetic waves can cause damage to living tissues and electronic devices.
What wave property is related to sound intensity?
Sound intensity is related to the amplitude of the sound wave, which is the measure of the maximum displacement of particles in a medium from their rest position. The greater the amplitude of a sound wave, the higher the intensity of the sound.
What gamma waves have?
Gamma waves have the shortest wavelength of any electromagnetic wave in the EM spectrum, the shortest wavelength means highest cyclic frequency, and highest intensity of any EM wave. (energy transferance by gamma waves is the strongest) *intensity is a measure of the height of the sine wave as opposed to to length, essentially more energy in a smaller crossectional area.
