An unpolarized light is travelling along Z axis through three polarizing sheets. The polarzing direction of the first and third sheet are respectively parallel to X axis and Y axis whereas that of the second one is at `60^(@)` to the Y axis. Then, the fraction of the initial light intensity that emerges from the system in about,
