Homework Help: Question about light reflection

  1. Apr 16, 2008 #1
    1. The problem statement, all variables and given/known data

    A diver shines a flashlight upward from beneath the water at a 23.0° angle to the vertical. At what angle does the light leave the water?

    2. Relevant equations
    I thought that i could use snell's law here...but i don't know what to do afterwards...

    3. The attempt at a solution

    angle of incidence is 23.... and the index of refraction is 1.333

    1.333 (sin 23) = 1 (sin x)

    is that about right?

    Write very clearly what x represents here. What do you feel that the question wants?
