1. ### A flat piece of glass

You have already got the refractive index for the glass plate, n(g) = 1.7219 For no refraction in water, total internal reflection occurs. Hence, 1.7219.sin(c) = 1.333.sin(90) where c is the incident angle (critical angle) where total internal refraction occurs. sin(c) = 1.333.sin(90)/1.7219...
