(a) the axes of two polaroids are placed at an angle so that the intensity of the incident unpolarized light is reduced to 1/3. what is that angle? (b) if unpolarized light passes through two polaroids whose axes are placed at an angle of 40 degrees, how much would the intensity of the light be reduced to?
Unpolarized light with an intensity of 34 units is passed through two successive polarizing filters, the first with its polarization axis aligned with the vertical and the second with its polarization axis rotated 55∘ from the vertical. find the intensity of the light after passing through the two polarizing filters. give your answer in same unit as the original light and with 3 significant figures.
