Total internal reflection occurs when the angle of incidence exceeds the critical angle. Therefore, the correct statement is:
**When the angle of incidence exceeds the critical angle.**
This phenomenon occurs when light attempts to move from a medium with a higher refractive index to a medium with a lower refractive index, such as from water to air. If the angle of incidence is greater than the critical angle, the light will not pass into the second medium but will instead be completely reflected back into the first medium.
