Total internal reflection can not take place when light goes from :
-
- glass to water
- water to glass
- water to air
- glass to air
- glass to water
Correct Option: B
For total internal reflection to occur the light must travel from a dense medium to a less dense medium (e.g. glass to air or water to air). It will not happen for light traveling from water (n=1.333) towards glass (n=1.52).
