Wavelength — In physics wavelength is the distance between repeating units of a propagating wave of a given frequency. It is commonly designated by the Greek letter lambda (λ). Examples of wave like phenomena are light, water waves, and sound waves. The… … Wikipedia
Wavelength dispersive X-ray spectroscopy — The Wavelength dispersive X ray spectroscopy (WDXRF or WDS) is a method used to count the number of X rays of a specific wavelength diffracted by a crystal. The wavelength of the impinging x ray and the crystal s lattice spacings are related by… … Wikipedia
wave length/wavelength — The distance traveled in one period or one cycle by a periodic disturbance. It is the distance between repeating units of a wave pattern. It is commonly designated by the Greek letter lambda (Λ). In a sine wave, the wavelength is the distance… … Aviation dictionary
Refractive index — Refraction of light at the interface between two media. In optics the refractive index or index of refraction of a substance or medium is a measure of the speed of light in that medium. It is expressed as a ratio of the speed of light in vacuum… … Wikipedia
Dispersion (optics) — This article is about dispersion of waves in optics. For other forms of dispersion, see Dispersion (disambiguation). In a prism, material dispersion (a wavelength dependent refractive index) causes different colors to refract at different angles … Wikipedia
Optical path length — In optics, optical path length (OPL) or optical distance is the product of the geometric length of the path light follows through the system, and the index of refraction of the medium through which it propagates. A difference in optical path… … Wikipedia
Near-field scanning optical microscope — Near field scanning optical microscopy (NSOM/SNOM) is a microscopic technique for nanostructure investigation that breaks the far field resolution limit by exploiting the properties of evanescent waves. This is done by placing the detector very… … Wikipedia
Self-focusing — is a non linear optical process induced by the change in refractive index of materials exposed to intense electromagnetic radiation. [Cumberbatch, E. Self focusing in Non linear optics , J. Inst. Maths Applics 6, 250 (1970)] Mourou, G. A. et al.… … Wikipedia
Heat — In physics, heat, symbolized by Q , is energy transferred from one body or system to another due to a difference in temperature. [cite book|author= Daintith, John |title=Oxford Dictionary of Physics|publisher=Oxford University… … Wikipedia
Normalized frequency (fiber optics) — In an optical fiber, the normalized frequency, V (also called the V number), is given by where a is the core radius, λ is the wavelength in vacuum, n1 is the maximum refractive index of the core, n2 is the refractive index of the homogeneous… … Wikipedia
