The rate (per foot) at which light is absorbed as it passes through water is proportional to the intensity, or brightness, at that point. A) Find the intensity as a function of the distance the light has traveled through the water. l is intensity, s is the distance traveled through the water, k>0 is the proportionality constant, and A represents the initial intensity of the light. l(s)=?B) If 20% of the light is absorbed in 10 feet, how much is absorbed in 20 feet? and 25%?round answer to 1 decimal place.
