Fraunhofer lines, английский
Fraunhofer was the inventor of the diffraction grating. he assigned letters to the black absorption lines in the solar spectrum. these resonance lines arise from energy absorption by elements in the outer atmospheres of stars that are cooler than the stellar gases below.
Fraunhofer zone (ut), английский
Zone, английский
- The section of a building that is served by one heating or cooling loop because it has noticeably distinct heating or cooling needs. also, the section of property that will be watered from a lawn sprinkler system.
- Зона
- A type of defense that assigns each defender to a particular area in front of or around his team`s goal in which he is responsible for marking any attacker that enters; often used in youth league games but rarely in professional competition.
- An area of the body
- See belt.
- [1] one of seven longitudinal belts into which geographers divide the globe. a central equatorial or torrid zone is bordered by tropical zones, followed by temperate zones and, finally, polar or frigid zones. [2] one of twenty-four latitudinal time zones, each covering 15° of longitude and centered on a meridian (except for adjustments to accommodate political boundaries). [3] to be “in the zone” means eligible for promotion.
- An area established and identified for specific reason, typically because a hazard exists.
- A business division of network rail with responsibility for the assets within a geographical area. during 2003, the zonal structure was replaced by a regional structure, and zones became regions. during 2004 the regions were restructured into territories

Fundamental, английский
- A основной; ко- ренной; базисный, главный, существенный frequency fusing a использующий фузию
- The lowest frequency in a complex sound wave.
Wavelength, английский
- Light is made up of electromagnetic waves; wavelength is the crest (peak)-to-crest distance between two adjacent waves.
- Для оптических сетевых устройств длина волны светового потока составляет 850, 1300, 1310 и 1550 нм
- The optical term for frequency. fiber optics generally uses the 850 nm, 1300/1310 nm, 1550 nm and 1625 nm wavelengths for transmission purpose due to the marriage of performance with light sources, optical fibers, and optical detector technologies

- The length of the light wave, usually measured from crest to crest, which determines its color. common units of measurement are the micrometer (micron), the nanometer, and the angstrom unit.
- The spatial period of a plane wave
- The distance between "waves" in the electromagnetic field, specified as angstroms or nanometers.
- The distance an electromagnetic wave travels in the time it takes to oscillate through a complete cycle. wavelengths of light are measured in nanometers (10-9 m) or micrometers (10-6m).
- The linear distance occupied by one complete cycle of vibration of an energy form from any given point to the next point characterized by the same phase.
- For light waves or sound waves, the distance between two successive points of a periodic wave in the direction of propagation, in which the oscillation has the same phase; the distance the wave travels in one period. for light waves three common units of wavelength are: micrometer, nanometer, and angstrom. wave molding, oundy molding, swelled chamfer, undulating molding, undy
- Длина волны wax 1. воск 2. парафин 3. пластичная глина way 1. путь; дорога 2. проход; переход 3. колея 4. направление, сторона 5. амер, расстояние
- The physical length between corresponding points of successive cycles of a wave. low frequencies have long wavelengths; high frequencies have short wavelengths.
- The distance between the crests of a wave in a radio signal, measured as the speed of light divided by the frequency in- hz.
- The distance between one peak of a wave and the next peak
- Light is measured by its wavelength (in nanometers) or frequency (in hertz). one wavelength. equals the distance between two successive wave crests.
- The distance between two points having the same phase in two consecutive cycles of a periodic wave, along a line in the direction of propagation.
- Distance between repeating values of a wave — for example, the distance from one peak to the next peak on a sine wave. wavelength is a fundamental descriptor when discussing wave behavior, system sensitivity, and diffraction effects.
- Distance between repeating values of a wave. for example, the distance from one peak to the next peak on a sine wave.
- Distance between repeating values of a wave. for example, the distance from one peak to the next peak on a sine wave. wavelength is generally measured in nanometers when considering uv-a radiation (for example, 365 nm). compare frequency.
- Distance between repeating units of a wave. for example, the distance from one peak to the next peak.
- Distance needed in the propagation direction for a wave to go through a complete cycle.7,21
