Question

What is Total Internal Reflection? Explain giving suitable example

Answer 1

Total internal reflection, in physics, complete reflection of a ray of light within a medium such as water or glass from the surrounding surfaces back into the medium. ... At all angles less than the critical angle, both refraction and reflection occur in varying proportions.

Answer 2

Here is your answer

Mate!!

Total internal reflection, in physics, complete reflection of a ray of light within a medium such as water or glass from the surrounding surfaces back into the medium. The phenomenon occurs if the angle of incidence is greater than a certain limiting angle, called the critical angle.

Example:

When light goes from a denser medium to a less dense medium, as the angle of incidence exceeds the critical angle, the ray reflects back to the denser medium. ... Total Internal Reflection is a very efficient reflection, as the loss of light energy is almost negligible.
