medium. Refraction of light is the most commonly observed phenomenon, but other waves such as sound waves and water waves also experience refraction. How...

optics, the refractive index (or refraction index) of an optical medium is a dimensionless number that gives the indication of the light bending ability...

Light Refracted is a two-movement composition for chamber ensemble by the American composer Jennifer Higdon. It was first performed on September 22, 2002...

phenomenon caused by refraction, internal reflection and dispersion of light in water droplets resulting in a continuous spectrum of light appearing in the...

Although large refracting telescopes were very popular in the second half of the 19th century, for most research purposes, the refracting telescope has...

the law of refraction) is a formula used to describe the relationship between the angles of incidence and refraction, when referring to light or other waves...

contact lenses, microscopes and refracting telescopes are all examples of this manipulation. There are many sources of light. A body at a given temperature...

because the eye is refracting more than necessary. Myopia can be corrected with a concave lens, which causes the divergence of light rays before they reach...

was a Nobel Prize-winner in 1911 for his research on the eye as a light-refracting apparatus, he described the 'schematic eye', a mathematical model of...

measuring how light is changed as it enters a person's eye. The majority of autorefractors calculate the vision correction a patient needs (refraction) by using...

light in glass travels at ⁠c/1.5⁠ ≈ 200000 km/s (124000 mi/s); the refractive index of air for visible light is about 1.0003, so the speed of light in...

atmospheric effects), caustics (to simulate light focusing by uneven light-refracting surfaces, such as the light ripples seen on the bottom of a swimming...

its top is a smaller version of the portrait, and at its bottom a light-refracting metallic likeness of an architectural feature from the parliament buildings...

equation. Standard refractometers measure the extent of light refraction (as part of a refractive index) of transparent substances in either a liquid this...

Refracting telescopes use a lens to focus light. The Swedish 1-m Solar Telescope, with a lens diameter of 43 inches, is technically the largest, with...

property of a material having a refractive index that depends on the polarization and propagation direction of light. These optically anisotropic materials...

Bragg reflector of alternating refractive index. When the scale of this pattern matches the wavelength of visible light, structural coloration arises:...

Atmospheric refraction is the deviation of light or other electromagnetic wave from a straight line as it passes through the atmosphere due to the variation...

telescope, which uses mirrors to collect and focus light, was invented within a few decades of the first refracting telescope. In the 20th century, many new types...

prism recombining the spectrum of light, to make possible interesting layouts of the sleeve in record shops. The light band emanating from the prism on...
