4/ A lineally polarized electromagnetic wave is sent through two sheets of polarizing material "The first sheet , A is oriented so its transmission axis makes an ande of 30" with respect to the incident electric field of the Wave , The second sheet B is oriented so that its transmission axis makes an angle of 90' with the incident electric field of the wave . The incident beam has an electric field of peak magnitude Es and average intensity so ) what is the peak value of the electric field amplitude after it goes through sheet A ? b )/ what is the average intensity of the wave after it passes through A ? ") What is the average intensity of the wave offel it passes through Is? D) suppose that 1 and Bare interchanged so that the ware is first incident upon B. What is the average wore intensity after passing through both polarizing sheets
