0. Total internal reflection is possible when light travels from
- Option : D
- Explanation : When light travels from denser medium glass to rarer medium (water) it bends away from the normal. Therefore angle of refraction is greater than the angle of incidence. For a particular angle of incidence which is greater than the critical angle, light scatters internal reflection i. e. returns in the denser medium (glass).
