    [SOLVED] Width of Aperture...please help!!!

    1. The problem statement, all variables and given/known data
    A point source of light illuminates an aperture 2.3 m away. A 10.2-cm-wide bright patch of light appears on a screen 1.02 m behind the aperture. How wide is the aperture?

    2. Relevant equations



    3. The attempt at a solution
    I thought it was just (.102)/(2.3 + 1.02) = 0.0307 m
