What is a microwave radiation?
Radio with mm to cm range wavelengths. It is longer wavelength than IR.
Is potassium bromide IR active?
Potassium bromide has transparent crystals in the range 0,25-25 μm; KBr is used in infrared spectroscopy.
What is IR radiation in Ozone layer?
IR stands for Infrared radiation. Ozone has nothing to do with IR.
Why KBr using in IR?
KBr is transparent to IR radiation, most alkali halides are transparent in ir
Difference between FTIR and IR?
IR deals with spectra itself and almost without any processing. FTIR transforms IR spectra using Fourier transformation which allows to find very specific frequencies (each element has its own FTIR spectra).
Why polystyrene film is used for IR calibration?
the polystyrene film is cover all the ir range.
What is the IR range of -OCH3 group?
1423-1473 cm-1
Why you can see the ir led through camera?
Most digital camera sensors are sensitive to a small range of IR, as well as visible light.
What are the disadvantages of infrared waves?
For short-range (within a room) point-to-point data communication, IR is easily interrupted - think of IR as light, and imagine all the ways a light beam can be messed with. For long-range (we had a 1-km link once), heavy fog/rain will attenuate the IR so much that communication slows/stops. IR has mostly been superseded by Wi-Fi/Bluetooth and other R.F. wireless technologies, for range, reliability and speed. Check out the IRDA for more info.
What is a microwave radiation?
Radio with mm to cm range wavelengths. It is longer wavelength than IR.
What is the difference between UV lamps and IR lamps?
One emits light in the ultra-violet range, and the other emits light in the infrared range.
Why are salt crystal cells used in IR spectroscopy instead of glass or quartz cells?
Glass and quartz cells have high absorbency's of photons in the IR range, these are better for analyses in the UV/Vis region. Salt crystal cells, however, typically absorb very little IR radiation, making them optimal for IR spec.
What is the difference between pir movement sensor and ir sensor?
Passive simply means that the unit does not emit IR light, but does detect it. All warm things emit some degree of IR. a PIR motion detector senses the difference between a warm body and the cold background. Active IR emits IR light to illuminate an area to be "seen" with it's CCD that is sensitive to IR. Most new Sony camcorders use active IR for "night vision". IR alone, with no modifier, simply refers to the spectrum of light known as Infra Red, which is slightly above human's vision range.
How you can see objects in IR images?
Your question requires qualification. There is near-IR and far-IR which covers the wide range of wavelengths of IR. IR images are all about us, but our eyes cannot see them. In order to view them, some sort of image converter is required. The near IR band, just beyond what the eye can see, is called Near-IR. In this range, silicon diode detectors do a fairly good job of converting the image signal to an electrical signal. As is the case for a digital camera, an array of Near-IR signal diodes are used to detect the image, which is converted to an array of digital signals. These signals can then be converted to RGB signals, similar to those used for a computer monitor and then viewed. This is a very common method of producing IR image conversion for viewing. There are also the Night Vision Goggles that are used to view infrared signals at night. The optical detection method is somewhat different, although similar in that a special IR detector is required.
What does IR mean on my schedule It says I will be taking SPANISH IR. What does IR mean?
IR stands for: Introduction Remedial.
Is potassium bromide IR active?
Potassium bromide has transparent crystals in the range 0,25-25 μm; KBr is used in infrared spectroscopy.
