(20 points) curious carl and his lab partner were trying to answer the question: "what is white light? " to do this, carl directed a beam of light through a glass that had been placed on a piece of white paper. as the beam of light came out the opposite side, a rainbow of colors was produced on the white paper. a) prism b) microscope c) convex lens d) color filter

When a vertical beam of light passes through a transparent medium, the rate at which its intensity i decreases is proportional to i(t), where t represents the thickness of the medium (in feet). in clear seawater, 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 "10" feet below the surface? (give your answer in terms of i0. round any constants or coefficients to five decimal places.)
