Calculate the critical angle for a glass to water interface (refractive index of water and glass are 3/4 and 4/3 respectively) |
|
Answer» You're given air-to-glass is 3/2 which can be written: aRg = 3/2; similarly ARW = 4/3 which ALSO means wRa=3/4 wRg (the target) = wRa x aRg = 3/4 x 3/2 = 9/8 We know SinC = 1/R so C = ARCSIN(1/R) = ArcSin(8/9)(LIKE ME NOW)Explanation: |
