Total Internal Reflection
Total internal reflection is a phenomenon in optics where light traveling through a medium reaches a boundary with another medium and, due to encountering a higher refractive index, is completely reflected back into the original medium. This occurs when the angle of incidence exceeds the critical angle, resulting in all incident light being reflected rather than refracted. Total internal reflection plays a crucial role in various optical devices and applications, such as fiber optics communication systems, where it enables efficient transmission of light signals over long distances with minimal loss.
