A horizontal 5.0 mW laser beam that is vertically polarized is incident on a polarizing sheet that is oriented with its transmission axis vertical. Behind the first sheet is a second sheet that is oriented so that its transmission axis makes an angle of 30° with respect to vertical. What is the power of the beam transmitted through the second sheet? What would the power of the beam transmitted through the second sheet be if the lazer beam was Unpolarized?
