Polarizers: Three polarizers with different axes of transmission will be placed in the path of an unpolarized laser beam with an intensity of 1000 W/m². The transmission axis of polarizer A is vertical (0°), that of B is rotated 35.5° clockwise with respect to vertical, and that of C is rotated 53.3° clockwise with respect to vertical. The polarizers can be placed in any order, but the second polarizer must be 522 mm from the first, and the third must be 229 mm from the second. (a) Find the arrangement of polarizers that maximizes the transmitted intensity and compute the maximum intensity. (b) Find the arrangement of polarizers that minimizes the transmitted intensity and compute the minimum intensity.

The company where you work has obtained and stored five lasers in a supply room. You have been asked to determine the intensity of the electromagnetic radiation produced by each laser. The lasers are marked with specifications, but unfortunately different information is given for each laser: Laser A: power = 2.6 W; diameter of cylindrical beam = 2.6 mm Laser B: amplitude of electric field = 480 V/m Laser C: amplitude of magnetic field = 8.7 x 10-6 T Laser D: diameter of cylindrical beam = 1.8 mm; force on totally reflecting surface = 6.0 x 10-8 N Laser E: average energy density in beam = 3.0 x 10-7 J/m3 Calculate the intensity for each laser, and rank the lasers in order of increasing intensity. Assume that the laser beams have uniform intensity distributions over their cross sections.
