Unpolarized light is incident on two ideal polarizing filters. The second filter’s axis is rotated through an angle θθ relative to that of the first filter. Part A If the intensity of light emerging from the second filter is 1/10 the intensity of the incident light on that filter, what is θθ? Express your answer in degrees to two significant figures. θθ = nothing ∘∘ SubmitRequest Answer Provide Feedback

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.)
