Experiments show that the ground spider Drassodes cupreus uses one of its several pairs of eyes as a polarization detector In fact, the two eyes in this pair have polarization directions that are at right angles to one another Suppose linearly polarized light with an intensity of 775 W/m² shines from the sky onto the spider and that the intensity transmitted by one of the polarizing eyes is 774 W/m². For this eye, what is the angle between the polarization direction of the eye and the polarization direction of the incident light?

Consider the figure below that shows unpolarized light with intensity I0 = 8.75 W/m2 passing through three ideal polarizing filters A, B, and C. The polarizing axes are set to:A: vertical (along the positive y-axis).B: θ1 = 38.0° clockwise with respect to the positive y-axis.C: θ2 = 34.5° counterclockwise with respect to the negative y-axis.Calculate the intensity of the light (in W/m2) after it has passed through polarizer C.
