How do I calculate the angle of incidence?

I need help calculating Angle of incidence and angle of refraction?

  • I still don't even know how calculate the angle of incidence and the angle of refraction. Can someone give me a simple description on how to do it. Thanks

  • Answer:

    N1Sine(A1) = N2Sine(A2) - Snell's law... A1 is the angle is incidence... A2 will be the angle of refraction... So... A2 = Sine^-1[(N1/N2)Sine(A1)] Good luck...
