Webreflection: the property of a propagated wave being thrown back from a surface (such as a mirror) Whenever you look into a mirror or squint at sunlight glinting off a lake, you are seeing a reflection. When you look at the text in a book, you are actually seeing the light that is reflected from it. WebKBe2BO3F2 (KBBF) is the only nonlinear optical crystal available to generate deep-ultraviolet (DUV) laser output by direct harmonic generation. High-precision refractive indices, including in the DUV region, were measured, and starting from a double resonance model of polarizability, new dispersion relations of the refractive indices were deduced from the … WebMar 5, 2024 · The splitting up of white light into its constituent colours by refraction is called dispersion. Here is a ray of light travelling from one medium to another: It moves faster in the upper medium than in the lower medium.
