The critical angle for the total internal reflection at the liquid air interface is 42.5 degrees. (a) If a ray of light traveling in the liquid has an angle of incidence of 35.0 degrees at the interface, what angle does the refracted ray in the air make with the normal? (b) If a ray of light traveling in air has an angle of incidence of 35.0 degree at the interface, what angle does the refracted ray in the liquid make with the normal?
