differential equation
Not what you're looking for?
When a vertical beam of light passes through a transparent medium, that rate at which its intensity I decreases is proportional to I(t), where t represents the thickness of the medium (in feet). In clear sea water, the intensity 3 feet below the surface is 25% of the initial intensity I0 of the incident beam. What is the intensity of the beam 15 feet below the surface?
