Definitions Of Refraction Of Light Flashcards
1
Q
Definition of refraction
A
Refraction is the bending of light as it passes from one medium to another of different optical density.
2
Q
Critical angle definition
A
Critical angle (c) is defined as the angle of incidence in an optically denser medium which the angle of refraction in the optically less dense medium is 90 degrees
3
Q
Total internal reflection definition
A
Total internal refraction is the complete reflection of light inside an optically denser medium at its boundary with an optically less dense medium.
4
Q
Refractive index
A
The refractive index is the ratio of the speed of light in vacuum to the speed of light in a medium.
