Two linear polarizing filters are placed one behind the other, so that their transmission directions are parallel to one another. a beam of unpolarized light of intensity io is directed at the two filters. what fraction of the light will pass through both filters? a.0.5 iob.0c.2 iod.0.25 ioe. io

a.0.5 Io

Explanation:

The fraction of light passing through the first polarizer will be

The fraction of light passing through the second polarizer will be

where

= Angle between the filters

here, as the transmission directions are parallel to one another

Hence, will pass through both filters
