When light transitions from a denser medium to a rarer medium, such as from glass to air, it can internally reflect. This phenomenon occurs due to the change in the refractive index at the interface. Total internal reflection is crucial ...

A stone at the bottom of a pond appears higher than its actual position due to refraction of light. As light travels from water to air, it bends away from the normal, causing the stone to appear at a shallower ...
Endoscopy, the technique used to investigate the stomach or other internal organs, is based on the phenomenon of total internal reflection. This principle allows light to be transmitted through flexible optical fibers, enabling visualization of internal structures with minimal invasive ...
A mirage is an example of refraction. It occurs when light passes through layers of air at different temperatures, bending the light rays. This bending creates the illusion of water or a distorted image on surfaces like roads or deserts, ...
A fish lying inside water appears slightly above its actual depth due to the refraction of light. When light passes from water to air, it bends away from the normal. This bending causes the fish to appear at a shallower ...
