WebRefraction is the phenomenon that causes a light ray to bend when it hits an optical lens surface (or other medium that can act to transmit light e.g. water). Refraction occurs … WebFeb 16, 2024 · Refraction effects are based on the fact that light travels more slowly in a denser medium. The ratio of the velocity of light in air to its velocity in the medium is called the refractive index of the medium for light of a particular colour or wavelength. The refractive index is higher for blue light than for light at the red end of the spectrum. WebRefraction Rule for a Converging Lens.
