The formation of a rainbow is due to the refraction, dispersion, and reflection of sunlight by water droplets in the atmosphere. Sunlight entering the droplets is refracted, split into its component colors, internally reflected, and then refracted again as it ...

Total internal reflection occurs when light travels from a denser medium to a rarer medium, with an angle of incidence greater than the critical angle. This phenomenon causes the light to be completely reflected back into the denser medium, rather ...
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, ...
