EXAMPLE 12 Transparency of a Lake If I, and I denote the intensity of light before and after going through a material and x is the distance (in feet) the light travels in the material, then according to the Beer-Lambert Law, In k = x where k is a constant depending on the type of material. (a) Solve the equation for I. The intensity of light in a lake diminishes with depth. (b) For a certain lake k = 0.025, and the light intensity is 1, = 14 lumens (Im). Find the light intensity at a depth of 20 ft.
