Question

Light that is polarized along the vertical direction isincident on a sheet of polarizing material. Only % of theintensity of the light passes through the sheet and strikes asecond sheet of polarizing material. No light passes through thesecond sheet. Suppose the first polarizer was turnedcounterclockwise from the maximal light intensity position. Whatangle does the transmission axis of the second sheet make with thevertical? Light that is polarized along the vertical direction isincident on a sheet of polarizing material.

Suppose the first polarizer was turnedcounterclockwise from the maximal light intensity position. Whatangle does the transmission axis of the second sheet make with thevertical?

Explanation / Answer

   from the given problem we can see that the angle2 that the second sheet makes with respect thevertical is given by    2 = 2+ 90o    where 1 is the angle givingthe orientation of the axis of the first sheet    with help of Malus’ law weget the ratio of the intensity passing through the firstsheet to the incident intensity as    S / So = 0.94    S = Socos21    S / So = 0.94              = cos21    1 =cos-10.94        =.....o    so the angle of the axis of the second sheetwith respect to the vertical will be    2 = 1+ 90o         =......o
