2. a. Light of wavelength 630 nm is sent through a rectangular aperture to a screen that is 3.00 m away. On the screen, the resulting central bright fringe is measured to have a width of 2.80 cm. Use this information to find the width of the aperture. b. Randomly polarized light of intensity 2.00 W/m' is incident on a pair of polarizing filters, Find the angle at which the second polarizer is rotated with respect to the first. given that the light has an intensity of 0.650 W/m after passing through the polarizers
