A beam of light polarized along the y axis and moving along the +z axis passes through two polarized sheets with axes of polarization oriented 30◦ and 70◦ relatives to the y axis. The final intensity of the beam is measured to be 61 W/m2. What is the initial beam intensity? Express your answer to the nearest W/m2.
One way to produce a beam of polarized light with intensity I and polarization angle θ would be to pass unpolarized light with intensity I0 through a polarizer whose transmission axis is oriented such that θTA=θ. How large must I0 be if the transmitted light is to have intensity I? Express your answer as a decimal number times the symbol I. For example, if I0=(1/4)I, enter 0.25 * I.

A beam of polarized light is sent into a system of two polarizing sheets. Relative to the polarization direction of that incident light, the polarizing directions of the sheets are at angles u for the first sheet and 90° for the second sheet. If 0.10 of the incident intensity is transmitted by the two sheets, what is u?
Light that is polarized along the vertical direction is incident on a sheet of polarizing material. Only 73% of the intensity of the light passes through the sheet and strikes a second sheet of polarizing material. After the second sheet, a total of 17% of the light passed through both sheets. What angle does the transmission axis of the second sheet make with the vertical (less than 90)?

An unpolarized beam of light (intensity I0) is moving in the x-direction. The light passes through three ideal polarizers whose transmission axes are (in order) at angles 0.0°, 48.0°, and 22.0° counterclockwise from the y-axis in the yz-plane. If the polarizer in the middle is removed, what is the intensity and polarization of the light transmitted by the last polarizer?
