Homework Help: Linearly polarized light and its field strength.

  1. Apr 9, 2009 #1
    1. The problem statement, all variables and given/known data

    if linearly polarized light has an electric field strength E, what is its field strength after it has passed through polarizing material that has a transmission axis oriented at an angle theta relative to the direction of E?

    2. Relevant equations

    3. The attempt at a solution
    i cant seem to get my head around this problem. any help would be greatly appreciated.

    When the transmission axis of two polarizing materials are perpendicular strength of electric field is zero. Hence electric field through second material must be Ecos(theta)
