If a beam of light with an angle of incidence

  1. Sep 23, 2012 #1
    1. The problem statement, all variables and given/known data

    The maximum depth of Lake Baikal, in Russia, is 1780.7 m, making it the world’s deepest freshwater lake. If a beam of light with an angle of incidence of 59.42o enters the water from the air, what is the horizontal distance between the point where the light enters the water and the point where it strikes the lake’s bottom?

    2. Relevant equations



    3. The attempt at a solution
