Applications of Electromagnetic Wave Intensity This relationship is particularly important in understanding the behavior of electromagnetic waves in various contexts, such as signal transmission, energy transfer, and interaction with matter. The intensity is directly proportional to the square of the amplitude, which means that small changes in the amplitude can lead to significant changes in the intensity. The equation for the intensity of an electromagnetic wave highlights the relationship between the intensity and the amplitude of the electric field. E is the amplitude of the electric field associated with the wave (V/m). c is the speed of light in a vacuum (3.00 x 10 8 m/s) and.ε 0 is the permittivity of free space (8.854 x 10 -12 F/m).I is the intensity of the electromagnetic wave.The intensity of an electromagnetic wave can be calculated using the following equation: Intensity gives us an idea about the strength or energy content of an electromagnetic wave and is directly proportional to the square of the amplitude of the wave. It is a scalar quantity and is measured in watts per square meter (W/m 2). Intensity (I) is defined as the amount of energy transported by an electromagnetic wave per unit time and per unit area.
