Direction of Light to our Eyes

  1. Aug 6, 2015 #1
    Hi everyone! I just wonder when I use a laser pointer to other direction. How come our eyes able to see it? Since the light is traveling towards the other direction and not to our eyes. Is there an equation associated with that or its just basic logic is needed to understand why this happen.

    You're seeing light that is scattered by dust in the atmosphere.
