Question Reference: IGCSE (Light) - Relation between critical angle and total internal reflection


Question:

What is critical angle and how is it related with total internal reflection?

Submited By:Rifaqat Ali Minhas On:16/08/15 03:10 PM
Solution:

Critical angle:

It is an angle of incidence in the denser medium for which angle of refraction in the rare medium is 90o

Total internal reflection:

If the angle of incidense in the denser medium is greater than critical angle, total internal reflection takes place.

What is critical angle and how is it related with total internal reflection?
