In SI system, unit of wavelength is meter. Any way meter is a large unit so we use Angstrom and some times nanometer. Angstrom (Ǻ) equals to 10 -10 m and nano metre equals to 10-9 m. The range of wavelength for visible light is from 3700 Ǻ to 7200 Ǻ.
A unit of radiation wavelength is the nanometer (nm), which is equivalent to one billionth of a meter. It is commonly used to measure the wavelength of electromagnetic radiation, such as light or X-rays.
waveLENGTH uses the same measurement as any length. The standard is metric, so everything's in metres (m). The first link describes the different lengths of the visible spectrum. Note that white light is a combination of all these frequencies. The second link describes how a nanometre (nm) is different from a milimetre (mm). http://eosweb.larc.NASA.gov/EDDOCS/Wavelengths_for_Colors.html http://www.knowledgedoor.com/1/Unit_Conversion/Power_Prefixes.htm

How does long wavelength radiation contribute to the greenhouse effect?
Long wavelength radiation, such as infrared radiation, is emitted by Earth's surface after absorbing solar radiation. Greenhouse gases in the atmosphere trap this long wavelength radiation, leading to a warming effect known as the greenhouse effect. This process helps regulate Earth's temperature by keeping the planet warm enough to support life.
What wavelength of radiation is reradiated by the Earth upward?
The Earth reradiates longwave infrared radiation, with a peak wavelength around 10 micrometers. This is due to the Earth's relatively cool temperature compared to the Sun, causing it to emit radiation in the infrared part of the electromagnetic spectrum.
What energy in the form of electromagnetic radiation most often associated with a wavelength that is visible to the eye?
Visible light is the energy in the form of electromagnetic radiation that is most often associated with a wavelength that is visible to the human eye.
Why does the Earth emit longer wave radiation than the Sun?
The Earth emits longer wavelength infrared radiation because it absorbs sunlight and re-radiates it as heat. The Sun, on the other hand, emits shorter wavelength radiation in the form of visible light because it is much hotter than the Earth.
Infrared radiation has a wavelength slightly longer than?
Infrared radiation has a wavelength slightly longer than visible light. It falls within the electromagnetic spectrum between microwaves and visible light, with wavelengths ranging from about 700 nanometers to 1 millimeter.
What is wave number of a radiation of wavelength 400nm?
The wave number is the number of wavelengths per unit length. It is calculated as the reciprocal of the wavelength. Therefore, for a radiation with a wavelength of 400 nm, the wave number would be 1/400 nm, or 2.5 x 10^3 m^-1.
Will people be affected by electromagnetic radiation?
that depends on the wavelength of the radiation. the shorter the wavelength the more damage it can do.
Which has the longest wavelength 1ultraviolet radiation 2gamma radiation 3 visible radiation 4 infrared radiation?
Gamma radiation has the shortest wavelength and ultraviolet radiation has a longer wavelength than gamma radiation. Infrared radiation would have a longer wavelength than ultraviolet radiation. So, the longest wavelength of the options given would be infrared radiation.
What are radiation units of measure?
The details depend on what type of radiation you are thinking about. Some units that apply to lots of types of radiation include:* Power * Intensity, which is power per unit area * Frequency and wavelength - many types of radiation come in waves.
Radiation with a wavelength 4.2 nm?
X rays have a wavelength of 4.2 nm.
How do you find the wavelength of gamma radiation?
You can find the wavelength of gamma radiation using the equation: wavelength (λ) = speed of light (c) / frequency (ν). The frequency of gamma radiation is typically given in hertz (Hz).
Because c the speed of electromagnetic radiation is a constant the wavelength of the radiation is....?
... inversely proportional to its frequency. This means that as the frequency of radiation increases, its wavelength decreases, and vice versa. This relationship is expressed by the equation λ = c / f, where λ is the wavelength, c is the speed of light, and f is the frequency of the radiation.
What is the smallest infrared radiation wavelength?
The smallest infrared radiation wavelength is approximately 0.7 micrometers (700 nanometers). This corresponds to the near-infrared region of the electromagnetic spectrum.
What is long wavelength radiation given out by stars?
Long wavelength radiation given out by stars is typically in the form of infrared radiation. This type of radiation has longer wavelengths than visible light and is emitted by stars as a product of their high temperatures. It is important for studying the properties and evolution of stars.
What is the frequency of radiation whose wavelength is 0.0000240?
12.5 terahertz. If your wavelength is in meters.
What has the shortest wavelength in radiation?
Gamma rays have the shortest wavelength in the electromagnetic spectrum.
What has the longest wavelength 1- Ultraviolet radiation 2- Gamma Radiation 3- Visible radiation 4- Infrared radiation?
4- Infrared radiation has the longest wavelength among the options provided.
