Textbook Question
Chapter 23, Problem 58P
A beam of polarized light passes through a polarizing filter. When the angle between the polarizing axis of the filter and the direction of polarization of the light is 30°, the intensity of the emerging beam is I. If you instead want the intensity to be I/2, what should be the angle between the filter axis and the original direction of polarization of the light?

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 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.
Only 13.0% of the intensity of a polarized light wave passes through a polarizing filter.
What is the angle between the electric field and the axis of the filter?

Consider a long cylindrical wire of radius r with a current I in the wire, with resistance R and voltage V.
