Two polarizers are oriented at 50 o to one another. Unpolarized light falls on them.
1. What fraction of the light intensity is transmitted?
2. Monochromatic light falls on a slit that is 2.10x10-3 mm wide. If the angle between the first dark fringes on either side of the central maximum is 29.0o(dark fringe to dark fringe), what is the wavelength of the light used?
