When a vertical beam of light passes through a transparent medium, the reason that its intensity I decreases is proportional to I(t), where t represents the thickness, in feet, of the medium. In clean sea water, the intensity at 3 feet below the surface is 25% of the initial intensity I0 of the incident ray. What is the beam intensity at 15 feet below the surface?
