WebQuestion: What happens when light is incident from air to water at an angle greater than the critical angle for the water-air interface, θ > 48.8o? The light is totally refelected … When light travels from a medium with a higher refractive index to one with a lower refractive index, Snell's law seems to require in some cases (whenever the angle of incidence is large enough) that the sine of the angle of refraction be greater than one. This of course is impossible, and the light in such cases is completely reflected by the boundary, a phenomenon known as total internal r…
