| Глоссарий по визуальному контролю и осмотру |
- Unwanted electromagnetic radiation that has a wavelength between 400 and 800 nm that is generated by a uv-a source but not filtered out of the emission spectrum. leaked visible light is generally perceived as purple or dark blue light and not accurately measured using a photometric sensor.4
- In fluorescent nondestructive testing, electromagnetic radiation with a wavelength between 400 and 760 nm that is generated by a uv-a source but not filtered out of the emission spectrum. leaked visible light is generally violet and not accurately measured using a photometric sensor. see also light contamination; photometer; radiometer; uv-a; uv-a filter; visible light.

Electromagnetic, английский
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

- 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

- The introduction of sewage, wastes, and/or chemicals (or other material) into a potable water supply that render it unfit for its intended purpose. contemporary style an imprecise term applied to any of a number of architectural modes popular from about the 1940s through the 1970s and beyond, sometimes included under the term modern architecture; often characterized by widely overhanging eaves, exposed roof beams, and front-facing gables with heavy piers that support the gables; often, a balcony with an overhanging sunscreen, roof decks, and a patio that may serve as an extension of the living area; another type has a facade and flat roof resembling that of the international style. continuous beam 251
- The action of contaminating something, or the state of being contaminated the contamination resulted from polluted water.
