Finding the Critical Angle for T.I.R.

  1. Jul 21, 2013 #1
    1. The problem statement, all variables and given/known data

    When light strikes an air-material interface from the air side, Brewster’s angle is 63°.
    What is the critical angle for total internal reflection for light striking the interface from
    the material side?


    2. Relevant equations

    tanθB=n2/n1

    sinθc=n1/n2
    (n2 is greater than n1)

    3. The attempt at a solution

    n1=1.000

    tan63=n2/1.000

    n2=1.963

    sinθc=(1.000/1.963)

    θc=31°
