Spectrum (visible & electromagnetic)
| Light Glossary |
The full range of electromagnetic wavelengths extends from the shortest gamma rays of 1 millionth mm to radio waves of 6 miles. buried in the middle is the visible spectrum, the tiny portion to which the human eye is sensitive. the spectrum can be "seen" when white light is intercepted by a prism or rain-drops. tip: it does not fully match what film "sees" and therein lie occasional surprises. see: ultraviolet and infrared.

Electromagnetic, английский
Occasional, английский
- Случайный
- A 1 случайный; 2 окка- зиональный equivalent
Ultraviolet, английский
- Electromagnetic radiation at wavelengths shorter than the violet end of visible light
- Ultraviolet. the electromagnetic radiation with wavelengths shorter than about 400 nm and not visible to the human eye.
- Ультрафиолетовый
- Invisible electromagnetic radiation defined between 100 and 380nm.
- The part of the electromagnetic spectrum that falls just below visible violet. ultraviolet (uv) coating – a coating that blocks out uv radiation up to 380+ nanometers.
- Electromagnetic radiation in the wavelength range of 4 to 400 nanometers.
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
- Distance in the direction of propagation of a periodic wave between two successive points at which the phase is the same. tel 203•377•8282 fax 203•378•2457 e-mail res_sales@oriel.com url www.oriel.com 9-17 polarization lenses optics prisms & filters beam splitters windows, substrates & mirrors properties of optical coatings optical materials
- 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

Ambient light, английский
- The general (and often undesirable) illumination surrounding the shooting or projection area; not exactly the same as available light or natural light. tip: use the term to ward off meddling clients, as in "i can`t light it your way because of the ambient light." they are likely to nod sagely.
- The light in the scene, as opposed to the light provided by the photographer with flash, photofloods, etc.
- Also referred to as available light, is the light that is occurring in the scene without adding any flash or light modifiers. this could be daylight, or man made light such as tungsten or fluorescent bulbs.
- Рассеянный свет; общая освещенность; общее освещение
- A type of light that appears as if it is coming from all directions. use this when you want to light all objects evenly.
- Фоновое освещение тонируемой сцены. равномерно распределяется по сцене, обеспечивая одинаковую освещенность всех поверхностей независимо от их ориентации. не исходит от конкретного источника света и не дает теней.
- Light in the environment as opposed to illumination provided by a visual test system.
- Свет в окружающей среде в отличие от освещения, обеспечиваемого системой визуального тестирования.
- Light in the environment as opposed to illumination provided by a visual testing system. ampere (a): si unit of electric current.4
- Light in the environment as opposed to illumination provided by a visual testing system.1
- Light in the environment as opposed to illumination provided by a testing system. ambient temperature; atmospheric
- Light in the environment as opposed to illumination provided by a testing system. ambient temperature; atmospheric temperature: temperature of surrounding atmosphere. also called dry bulb temperature. compare standard atmospheric conditions. angstrom (a): disused unit of length. 1 a = 0.1 nm. see also wavelength.
Lighter`s block, английский
The frightful sensation of facing an unlit set with no notion where to start. the paralysis can be conquered by plane lighting and motivated lighting methods. quote from an academy award-winning cinematographer: "the first day i come on a set, i usually don`t know what i want to do; i feel like i`ve just graduated from usc [film school] . . . it takes me a little while to get my courage and spirit up." - conrad hall [ml]
