Optics problem

  1. Sep 16, 2004 #1
    imagine that i have a pair of LEDs throwing light on the same point on a piece of paper. This is possible if the LEDs are inclined equally at an angle to the normal coming out of paper, right?

    now if i consider two rays hitting the paper at the same point, then where can i explain the presence of the reflected ray as, is it:

    1) along the normal coming out of the paper
    2) partly along this normal and partly through one of the paths of incidence(since angle of incidence = angle of reflection).
    3) scattered everywhere.

    or is it any other answer. :confused:
    help is appreciated.
