Homework Help: Apparent Depth?

  1. Aug 8, 2007 #1
    1. The problem statement, all variables and given/known data
    Instead of calculating apparent depth (for example, a penny in a glass of water appears to be closer to the surface than it actually is), instead of finding the angle of refraction and using snell's law, can I use the following:

    Apparent Depth = Actual Depth x (n air / n water)
    ?

    Yes, that relationship will work for this situation. It comes ultimately from applying Snell's Law and the small angle approximation to the given problem.
