The Beer-Lambert Law. A beam of light enters a medium such as water or smoky air with initial intensity
The constant
(“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
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.
