Refraction - Wikipedia The refractive index of air depends on the air density and thus vary with air temperature and pressure Since the pressure is lower at higher altitudes, the refractive index is also lower, causing light rays to refract towards the earth surface when traveling long distances through the atmosphere
Refraction | Definition, Examples, Facts | Britannica refraction, in physics, the change in direction of a wave passing from one medium to another caused by its change in speed For example, waves travel faster in deep water than in shallow
REFRACT | English meaning - Cambridge Dictionary When a laser beam is focused onto a dielectric sphere, the rays incident on the particle are reflected and refracted at the surface The waves are refracted according to the ordinary refraction law deduced for non-moving magnetoactive plasmas
Refract - definition of refract by The Free Dictionary To deflect (light, for example) from a straight path by refraction 2 To alter by viewing through a medium: "In the Quartet reality is refracted through a variety of eyes" (Elizabeth Kastor) 3 Medicine To determine the refraction of (an eye, for example)
REFRACT definition and meaning | Collins English Dictionary When a ray of light or a sound wave refracts or is refracted, the path it follows bends at a particular point, for example when it enters water or glass As we age, the lenses of the eyes thicken, and thus refract light differently [VERB noun] surfaces that cause the light to reflect and refract [VERB]

REFRACT Definition Meaning | Dictionary. com Explanation Things that refract light — like lenses and prisms — bend it If you've looked through a water droplet on a car windshield, you've seen water refract light You're most likely to come across the verb refract when you're studying physics and the properties of light waves
