Homework Help: Waves Unit- Angle of Incidence

  1. Mar 8, 2012 #1
    1. The problem statement, all variables and given/known data

    2. Relevant equations

    3. The attempt at a solution
    I'm not really sure on the approach to take for this question. Since it proves 2 angles, Snell's Law could prove to be beneficial.

    Thanks for the help!

    First , use the snell's law on the bottom surface to connect the critical angle to the refractive index of the block. For the vertical surface, the angle of transmission is [itex]90-\theta_c[/itex] using basic geometry. then use snell's law again at the vertical surface. at the vertical surface angle of incidence is [itex]\theta_1[/itex]
