When light strikes the surface of a medium such as water or glass, its intensity decreases with depth. The Beer-Lambert-Bouguer law states that the percentage of decrease is the same for each additional unit of depth. In a certain lake, intensity decreases about 75% for each additional meter of depth. (a) Explain why intensity I is an exponential function of depth d in meters. O Intensity I is an exponential function of depth since I increases by an increasing percentage as a function of depth.
