what is meant by total internal reflection write its consequences
Answers
Answer:
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.

1)What are consequences of total internal reflection?
→We point out that the phenomenon of total internal reflection appearing on interaction of an electromagnetic wave, incident from a dielectric at the corrugated interface separating this medium from vacuum, can give rise to very large reflectivities (close to 100%).
•What are the consequences and applications of total internal reflection?
›Applications of Total Internal Reflection of Light:
→ The brilliance of a diamond is due to total internal reflection. Optical fibre works on the principle of total internal reflection. This phenomenon is used in many optical instruments like telescopes, microscopes, binoculars, spectroscopes, periscopes etc.
•What is total internal reflection class 10th?
✓Hint: Total internal reflection is the phenomenon of bouncing back of light in the same medium after striking the boundary of a rarer medium. This happens when the angle of refraction exceeds 90∘. In such a case Snell's law becomes invalid and reflection takes place instead of refraction.
