A source emits a beam of light with a wavelength of 525nm and an intensity of 500W/m^2, the beam falls on a system of three polarizers where the second and third polarizers form angles of 30° and 45° respectively with respect to the first polarizer. Then the beam passes through an opening with a width of 0.2 mm forming an interference pattern on a screen located at a distance of 1.2 m. Now determine the following: a) the intensity of the beam after passing through the system of polarizers b) the angle and height with which the first minimum is formed on the screen c) the numerical value of the ratio between the intensity at the 1.5mm point with respect to the intensity of the original source
