Expert Answer
The intensity of a light wave is defined as the amount of energy that passes though unit area perpendicular to the direction of the wave per unit time.
Now, intensity is directly proportional to the square of the amplitude.
Hence, one can say that with amplitude of light changing, its intensity also changes and so does the energy.
