A plane wave with a wavelength of 500 nm is incident normally ona single slit with a width of 5.0 x 10^-6 m. Consider waves that reach a point on a far-away screen such thatrays from the slit make an angle of 1.0° with the normal. The difference in phase for waves from the top and bottom of the slit is .
A) 0
B) 0.55 rad
C) 1.1 rad
D) 1.6 rad
E) 2.2 rad

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.)
