Total Internal Reflection
The complete reflection of a light ray at the boundary of two media when the beam travels from the medium with a higher refractive index to low refractive index is known as total internal reflection.
Condition for TIR
- Light should be travelling from Denser Medium(High Refractive Index) to Rarer Medium(Low Refractive Index)
- If the incidence angle is larger than the critical angle.
Application of TIR
- TIR is used in Optical fiber.
- It is binocular, telescope, periscope.
- TIR concept is used in Diamond.
- TIR is used in the formation of Mirage
