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.
