The Beer-Lambert Law. A beam of light enters a medium such as water or smoky air with initial intensity I 0 . Its intensity is decreased depending on the thickness (or concentration) of the medium. The intensity I at a depth (or concentration) of x units is given by I = I 0 e − μ x . The constant μ (“mu”), called the coefficient of absorption, varies with the medium. Use this law for Exercises 62 and 63. Light through sea water. Sea water has μ = 1.4 and x is measured in meters. What would increase cloudiness more – dropping x from 2m to 5m or dropping x from 7m to 10m? Explain.
