Total internal reflection of light occurs when light travels from a denser medium to a less dense medium and the angle of incidence is greater than the critical angle. The critical angle is the angle of incidence in the denser medium when the angle of refraction in the less dense medium is 90 degrees.

- 3. CONDITION The two conditions for total internal reflection to occur are: Light enters from a denser medium towards a less dense medium The angle of incidence in the denser medium is greater than the ciritical angle of the medium
- 4. Critical Angle (c) The angle of incidence in the denser medium when the angle of refraction in the less dense medium is 90 o .
