The relationship between electromagnetic amplitude and power is defined by the principle that the square of the amplitude of the electric field correlates directly with the irradiance (intensity) of the wave. This intensity is measured in watts per square meter (W/m²). To determine amplitude, one can measure the power or irradiance of a monochromatic wave and infer the amplitude from these measurements. This method provides a practical approach to understanding electromagnetic wave properties.
