Plane polarized light is sent through two consecutive polarizers, the first having its plane of polarization in the same direction as the incident light and the second having its plane at 90 to the original plane of polarization. A third polarizer, with plane of polarization at 60 to the original plane of polarization, is placed between the two other polarizers. What fraction of the original intensity now gets through?
a. 0.56
c. 0
b. 0.19
d. 0.25
