Total internal reflection and it's effects
Answers
*Answer*
*Explanation*
Answer:
Total internal reflection is a phenomenon in which the light rays reflects into the same medium where it came from.
Explanation:
When light rays enter from a denser medium to a rarer medium, after refraction, they will bend away from the normal. If the incident angle is greater than the critical angle, the rays are observed to reflect back into the same medium where they came from. This phenomenon called total internal reflection (TIR) has many applications in daily life.
The main application of TIR is in optical fibers. They are used widely in the telecommunication field. The optical signals are made to undergo TIR inside the optical fiber. These signal can now be transported to long distances without much loss in their energy. Optical fibres have an important role in the fast growth of the telecommunication field.
