chat the axes of transmission of the second and third find the intensity of light emerging from each filter if filters are 30° and 75° to that of the first, respectively. Three polarizing filters are arranged in such a way Assuming that the first polarizer is an ideal polarizer, b=12 W/m? 75° e original intensity is 12 W/m?. ゆ、=75°-30°=45° !! Given: Ø2= 30° I=12 W/m? Solution: (12 W/m³) after passing through the first filter = 2 =6 W/m? 2 1. after passing through the second filter = Imax cos o = 1, cos²o, = (6 W/m²)cos²30° = 4.5 W/m after passing through the third filter = I cos'o=1, cos'ó, = (4.5 W/m²) cos² 45° =2.25 W/m* %3D max Practice Exercise 7.7 Suppose that in Sample Problem 7.7, the orientation of the second and third filters are interchanged. Find the intensity of light emerging from each filter.
