Yes.

Lambert's law is a cosine function describing reflected light intensity. In practical terms it means you see maximum light intensity when you look head on at something, but the intensity drops off as you move to one side or the other. A graph of the rate at which it drops off mimics the cosine graph.

The Lambert-Beer law is the base of absorption spectrophotometry.

The chemistry and scientific equation for the Beer Lambert Law is A=EBC. This equation can be used to calculate the Beer Lambert law, and you can use it yourself.
