It spells "critical" correctly
A critical angle refers to the highest angle the light can possibly refract into or between objects without disappearing. ie = light going from crystal into water, the critical angle is 47degrees.
The critical angle is not the same thing as the angle of incidence. There is a reason the confusion. The critical angle is defined as the smallest angle of incidence which results in total internal reflection. Every plane wave incident on a flat surface has an angle of incidence. That can be any angle. When a wave travels from a dense medium to a less dense medium, there comes an angle of incidence where there is no transmission into the less dense medium. We say then that for an angle of incidence above the "critical angle" the result is total internal reflection. It is also true that with Snell's law, the critical angle is the particular angle of incidence which would result in a 90 degree angle of refraction.
explain what is a socialite angle?
46 degrees
Explain critical clearing angle calculation methods of improving stability
The definition of critical angle is the angle of incidence that refraction can still occur.
because a smaller critical angle means that it is easier for total internal reflection to occur, which is the desirable quality in an optical fibre.

The critical angle is the angle of incidence at which the light is refracted at an angle of 90 degrees. The critical angle can be calculated using Snell's Law: sin(critical angle) = 1 / refractive index. For diamond (n=2.42) to air (n=1), the critical angle is approximately 24.4 degrees.

Because of the difference in the density of the materials.
The critical angle for perspex and water is approximately 41 degrees. This means that any light ray entering perspex from water at an angle greater than 41 degrees will be totally internally reflected within the perspex.
You will get more total internal reflection with a medium that has a smaller critical angle. A smaller critical angle means that light is more likely to be reflected back into the medium rather than refracted out of it.
Yes, there is a critical angle for light traveling from glass to water. This critical angle is the angle of incidence that results in light being refracted along the interface between the two mediums, rather than being transmitted into the other medium. The critical angle can be calculated using Snell's Law.
