Light Refracted through a Prism 2? - photobucket index.of
Search the largest value that the angle of May without light refracted through the prism of the face of the CA if the prism is immersed in water (1.33) with a refractive index.
Express your answer in degrees. Ignoring surface reflections of British Columbia.

The angle of incidence of light on the surface of AC (90-alpha). This must be greater than the critical angle for TIR occur.
Sin (critical angle) = refractive index of water / glass refractice index = 1.33/1.58 = 0.0.842
Critical angle = sin-1 0.633 = 57.33 degrees
Alpha = 90 (or more) 57.33
\\ \\ \\ \\ Alpha \\ \\ \\ \\ u0026lt; (or equivalent) 90 to 39.27 = 32.67 degrees
Maximum angle of alpha is 32.67 degrees
