Unpolarized light [of intensity I0] fallson two polarizer sheets whose axes are at right angles.
(a) What fraction of the incident lightintensity is transmitted? I0 (b) What fraction of the incident light is transmitted if a thirdpolarizer is placed between the first two so that its axis makesa 65° angle with the firstpolarizer? I0 (c) What fraction of the incident light is transmitted if the thirdpolarizer is placed in front of the first sheet so that its axismakes a 65° angle with thefirst polarizer? I0
