The BeerLambert Law. A beam of light entersa medium such as water or smog with initialintensity I0. Its intensity decreases depending onthe thickness (or concentration) of the medium.The intensity I at a depth (or concentration) ofx units is given byI = I0e-mx.The constant m (the Greek letter mu) is calledthe coefficient of absorption, and it varies with themedium. For sea water, m = 1.4.a) What percentage of light intensity I0 remainsin sea water at a depth of 1 m? 3 m? 5 m?50 m?b) Plant life cannot exist below 10 m. What percentageof I0 remains at 10 m?
