DHAVAL TRIVEDI - Invidious

When light travels from a denser medium (like water) to a rarer medium (like air), it bends away from the normal at the interface. There's a specific angle of incidence beyond which total internal reflection occurs instead of refraction. That angle is called the critical angle.

Critical Angle:

The critical angle is the angle of incidence in the denser medium (water) for which the angle of refraction in the rarer medium (air) becomes 90°.
