    When an unpolarized light of intensity \[{{I}_{0}}\] is incident on a polarizing sheet, the intensity of the light which does not get transmitted is                                                          [AIEEE 2005]

    A)            Zero                                         

    B)            \[{{I}_{0}}\]

    C)            \[\frac{1}{2}{{I}_{0}}\]     

    D)            \[\frac{1}{4}{{I}_{0}}\]

    Correct Answer: C

    Solution :

               If an unpolarised light is converted into plane polarised light by passing through a polaroid, it's intensity becomes half.
