An unpolarized laser has an average power of .6 mW. At a distance of 10 m it forms a circle with a diameter of 2 mm. Intensity = 5.23 x 10^-4. Erms= .444 v/m. Brms= 1.48 x 10^-9 T. after traveling 10 m, the laser goes through two polarizers, the second having a polarization of 40 degrees relative to first. Howlong does it take the laser light to travel the 10 m Distance? If the polarizer has an index of refraction of 1.45, what is the speed of light in the polarizer?
