However, for any angle of incidence greater than or equal to the critical angle θcrit, all of the incident light reflects (therefore, none refracts), a phenomenon called total internal reflection. See Figure 33.13a. When θa = θcrit, θb nb = 90˚. Therefore, Snell’s law gives na sin θcrit = nb sin 90˚ ...
