Homework Help: Index of refraction

  1. Apr 28, 2004 #1
    In this figure the path of the light passes from air to glass. Calculate the index of refraction
    n1 = air = 1
    n2 = glass = ?
    Sin theta 1 = 30degrees
    sin theat 2 is = 20 degrees

    formula used n2 = n1*sin theta 1 / sin theta 2

    sin of 30/ sin of 20 = n2 = 1.46 is this correct
    hope the attachment went through will have to see before making judgement
