critical angle
This term is a technical specification used primarily in optics and physics. It describes a precise threshold of incidence; if the angle of light is smaller than this value, the light escapes the medium, but if it is larger, the light is trapped.
This phenomenon is the foundational principle behind the operation of fiber optic cables and the shimmering effect of mirages. As a specialized scientific term, it is almost exclusively used in academic, engineering, or technical contexts and does not have a metaphorical or casual application in general English conversation.
Meanings
Examples
The light ray must exceed the critical angle to achieve total internal reflection.
What happens when the angle of incidence is exactly the critical angle?
I wonder if the critical angle changes significantly as the temperature of the liquid rises.
The fiber optic cable works by keeping the light trapped via the critical angle.

If you look up from underwater, you can see a shimmering surface beyond the critical angle.
The beam of light hit the boundary at an angle greater than the critical angle.
We need to determine the refractive indices to find the critical angle.
