Linearly polarized light is incident on a single polarizing disk with the direction of the electric field vector parallel to the direction of the transmission axis. Through what angle should the polarizer be rotated so that the intensity in the transmitted beam is reduced by a factor of 5.0?

At an instant in time, the electric and magnetic fields of an electromagnetic wave are given by = -8.88 x 10-³ V/m and B = -2.96 x 10-11 T. Find the Poynting vector for this wave. (Express your answer in vector form. W/m² S =

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?

An unpolarized beam of light with an intensity of 5000 W/m2 is incident on two ideal polarizing sheets. If the emerging light has an intensity 0.200 times the original intensity of the incident beam, what is the angle between the two polarizers?
