A ray of light travelling in a transparent medium of refractive index ...
For total intemnal reflection (TIR)
μ = √2
So, μ = 1.40
μ = √2
So, μ = 1.40

A ray of light travelling in a transparent medium of refractive index ...
A ray of light traveling in a transparent medium of refractive index undergoes refraction. Refraction is the bending of light as it passes from one medium to another. The refractive index of a medium is a measure of how much the medium slows down the speed of light compared to its speed in a vacuum.
The refractive index is defined as the ratio of the speed of light in a vacuum to the speed of light in the medium. It is denoted by the symbol "n" and is a dimensionless quantity. The refractive index of a medium determines the angle at which the ray of light will bend when it enters or exits the medium.
When a ray of light passes from a medium with a lower refractive index to a medium with a higher refractive index, the ray bends towards the normal (an imaginary line perpendicular to the surface of the medium). This is called refraction towards the normal. Conversely, when a ray of light passes from a medium with a higher refractive index to a medium with a lower refractive index, the ray bends away from the normal. This is called refraction away from the normal.
The amount of bending that occurs depends on the difference in refractive indices between the two media and the angle of incidence of the ray of light. This relationship is described by Snell's law, which states that the ratio of the sine of the angle of incidence to the sine of the angle of refraction is equal to the ratio of the refractive indices of the two media.
In summary, a ray of light traveling in a transparent medium of refractive index undergoes refraction, which is the bending of light as it passes from one medium to another. The amount and direction of bending depend on the refractive indices of the two media and the angle of incidence of the ray of light.
