Homework Help: Snell´s Law

  1. Mar 22, 2010 #1
    1. The problem statement, all variables and given/known data

    A light beam incident on a glass slide at an angle of 60 ˚, being partly reflected and partly refracted. It notes that reflected and refracted beams are each at 90 ˚ What is the refractive index of glass?

    2. Relevant equations

    n1sinσ1 = n2sinσ2

    3. The attempt at a solution

    σ1 = 60°
    σ2 = 30°

    sinσ1 / sinσ2 = n

    So, is this right?
