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 ...
An object above the water surface appears higher than its actual position to a person underwater due to the refraction of light. As light travels from air to water, it bends towards the normal, causing the object to appear elevated, ...
A compound microscope is an optical instrument designed for magnifying small objects. It uses multiple lenses to achieve high magnification. Light passes through the specimen and is magnified by an objective lens, then further enlarged by an eyepiece lens. This ...
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 ...
