Question

Although light loses some intensity every time is passes through a polarizing filter, a longer series of filters can transmit more of a beam's intensity than a shorter series while rotating its polarization axis by the same angle. Demonstrate this by calculating the percentage of incident intensity (I/I0) transmitted through these two sets of filters: <?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" /?>

A vertically polarized beam passes through two filters, tilted 30 degrees and 60 degrees from the vertical.

A vertically polarized beam passes through four tilter, tilted 15, 30, 45 and 60 degrees from the vertical.

Explanation / Answer

I/10 percentage=0.021*0.036/0.14*0.145*0.160*0.180 from angle of tilt
