refraction
의미: The change in direction of a wave as it passes from one medium to another, caused by a change in the wave's speed.
Refraction is most commonly observed with light: a straw in a glass of water appears bent because light refracts as it passes between air and water. This principle underpins the design of lenses, spectacles, and optical instruments. Snell's law provides the mathematical relationship between angles of incidence and refraction. In ophthalmology, 'refraction' also refers to an eye test measuring how the eye bends light.
