Explanation:
Intensity is defined as the rate at which energy is transmitted through a unit area perpendicular to the direction of propagation of the wave. The intensity of a plane electromagnetic wave is proportional to the square of the amplitude of its electric field.
I = 1/2εcE²
where I represents the intensity, ε represents the permittivity of free space, c represents the speed of light, and E represents the amplitude of the electric field.
To find the proportionality between the intensity and the electric field, we can simplify the above equation as follows:
I ∝ E²
Therefore, the correct option is D, i.e., the intensity of a plane electromagnetic wave is proportional to the square of its electric field.
Conclusion:
The intensity of a plane electromagnetic wave is proportional to the square of its electric field. This relationship is important in various applications of electromagnetic waves, such as in the design of antennas and in the measurement of electromagnetic radiation.
