When a light ray passes from one medium to another, its frequency remains the same while its wavelength changes. The speed of light varies in different media, causing the wavelength to alter to maintain the constant frequency characteristic of the ...
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 ...
Diamond appears shiny primarily due to its high refractive index and strong dispersion of light. When light enters a diamond, it undergoes multiple internal reflections at different angles, enhancing its brilliance and sparkle. This phenomenon is known as diamond’s “fire” ...
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, ...
