Total internal reflection is a phenomenon that occurs when a light ray traveling from a denser medium to a less dense medium is reflected back into the denser medium instead of being refracted. This occurs when the angle of incidence is greater than the critical angle, causing all of the light to be reflected back. Total internal reflection is commonly seen in optical fibers and prisms.

Total internal reflection (TIR) is a phenomenon that occurs when a light wave traveling in a medium with a higher refractive index strikes a boundary with a medium with a lower refractive index at an angle greater than the critical angle.
At this critical angle, the refracted wave is bent so that it travels along the boundary between the two media. As the angle of incidence increases beyond the critical angle, the refracted wave disappears, and the light wave is completely reflected back into the higher refractive index medium.
TIR is a fundamental principle of optics and has applications in various optical devices, such as prisms, lenses, and fiber optics. It is also responsible for the shimmering appearance of mirages and the bright colors seen in soap bubbles and oil slicks.
