TIR -
1. Light is reflected back into the same medium
2. When angle of incidence exceeds the critical angle for the given pakr of media
3. Light must travel from denser to rarer medium.
4. No loss of energy 100% reflection
5. No refraction
Critical angle-
The last angle for which refraction takes place for which corresponding angle of orefraction is 90 degrees.
Light must travel from denser to rarer medium.
