Question : A light ray travelling from denser to rarer medium at an angle of incidence more than the critical angle of the concerned media pair suffers:
Option 1: reflection
Option 2: refraction
Option 3: diffraction
Option 4: total internal reflection
Correct Answer: total internal reflection
Solution : The correct answer is total internal reflection .
Total internal reflection is the complete reflection of a light ray within a medium, like water, or glass, back into the same medium. This phenomenon occurs when the angle of incidence surpasses a critical angle. It typically happens at the interface of two transparent media, where the incident ray in the medium with a higher refractive index approaches the other medium at an angle greater than the critical angle.
