The maximum depth of Lake Baikal, in Russia, is 1637 m, making it the world's deepest freshwater lake. If a beam of light with an angle of incidence of 60.0 degrees 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?
- I understand that you have to use Snell's Law for this problem but I do not understand what the problem is asking. Does it want to know what the angle of refraction is?

    find the angle of refraction. then,horizontal distance from the verticalpoint of entry at surface is


    distance= 1637*tangent(anglerefraction)

    Thanks so much!
