What happens to the intensity of light as the distance from the source increases, according to the inverse square law?

The intensity of light decreases as the distance from the source increases, which is a fundamental principle of the inverse square law. This law states that the intensity (or brightness) of light is inversely proportional to the square of the distance from the light source. This means that as you move away from the source, the spread of light over a larger area reduces the intensity experienced at any specific point.

For example, if you double the distance from a light source, the intensity of light reduces to one-fourth of its original value, because intensity falls off with the square of the distance (1/distance²). Therefore, as the distance increases, the intensity continues to decrease progressively, aligning with the explanation provided by the inverse square law.
