Define critical angle for a pair of optical media. Obtain the relation between critical angle and the refractive index of a medium with respect to air.
Answers
Answer:
In Optics, The angle of incidence to which the angle of refraction is 90° is called the critical angle. The ratio of velocities of a light ray in the air to the given medium is a refractive index. Thus, the relation between the critical angle and refractive index can be established as the Critical angle is inversely proportional to the refractive index.
Critical Angle And Refractive Index
The relationship between critical angle and refractive index can be mathematically written as –
SinC=1μab
Where,
C is the critical angle.
μ is the refractive index of the medium.
a and b represent two medium in which light ray travels
