What is the difference between reflectivity and reflectence?
reflectivity is the fraction of incident radiation reflected by a surface. In general it must be treated as a directional property that is a function of the reflected direction, the incident direction, and the incident wavelength. However it is also commonly averaged over the reflected hemisphere to give the hemispherical spectral reflectivity:reflectance a measure of the ability of a surface to reflect light or other electromagnetic radiation, equal to the ratio of the reflected flux to the incident flux.
What is the relationship between absorbance intensity of incident radiation and intensity of transmitted radiation?
The relationship between absorbance intensity of incident radiation and intensity of transmitted radiation is inverse. As absorbance increases, transmitted intensity decreases. This is due to the absorption of light energy by the material, leading to a reduction in the amount of light passing through it.
How can the frequency of incident radiation be varied?
The frequency of incident radiation can be varied by changing the energy level of the source emitting the radiation. For example, in the case of electromagnetic radiation like light, increasing the energy of the source (such as a higher voltage in the case of X-rays) will result in higher frequency radiation. Similarly, for radioactive decay processes, the frequency of emitted radiation can be controlled by manipulating the radioactive material's properties.
When light is incident on a black body?
When light is incident on a black body, it is mostly absorbed rather than reflected. This absorption results in an increase in the body's temperature. The body then emits thermal radiation, with the amount and wavelength of this radiation being determined by the body's temperature.
What is net radiation instrument?
A net radiation instrument is a device used to measure the balance between incoming and outgoing radiation at the Earth's surface. It typically consists of sensors that can measure both incoming solar radiation and outgoing terrestrial radiation, allowing for the calculation of the net radiation flux. This information is important for understanding the energy balance of the Earth's surface and can be used in various environmental and meteorological studies.
What is an albedometer?
An albedometer is an instrument used to measure the albedo - the fraction of incident light or radiation reflected by a body - of a surface.
What is an absorption coefficient?
An absorption coefficient is a measure of the absorption of electromagnetic radiation as it passes through a specific substance - calculated as the fraction of incident radiation absorbed by unit mass or unit thickness.
What is incident radiation?
Radiation is a general term for the energy transmitted through space.Incident radiation is a term used when referring to the radiation hitting a specific surface. For instance, the incident radiation for a solar panel is the total amount of radiation hitting the surface of the solar panel. This is in contrast to direct beam radiation which refers to only that radiation which arrives in a strait line from the sun. (It differs in that total incident radiation includes additionally the component of diffuse radiation.)
What is an absorptance?
An absorptance is a ratio measuring absorbed radiation and incident radiation - to show how well a particular surface absorbs radiation.
What is the difference between reflectivity and reflectence?

How does the greenhouse effect work relative to earth's energy balance?
The balance of incident Solar radiation as compared to the Re-Radiation of the same incident Solar radiation is skewed so that the Re-Radiation is cancelled and the Heat - easily in infra-red form - is Retained at and by the Earth.
Most of the radiation incident upon the Earth falls within the?
Most of the radiation incident upon the Earth falls within the visible and near-infrared portions of the electromagnetic spectrum.
What is the relationship between absorbance intensity of incident radiation and intensity of transmitted radiation?
The relationship between absorbance intensity of incident radiation and intensity of transmitted radiation is inverse. As absorbance increases, transmitted intensity decreases. This is due to the absorption of light energy by the material, leading to a reduction in the amount of light passing through it.

The frequency of incident radiation can be varied by changing the energy level of the source emitting the radiation. For example, in the case of electromagnetic radiation like light, increasing the energy of the source (such as a higher voltage in the case of X-rays) will result in higher frequency radiation.

What is the definition of radiation use efficiency and light use efficiency?
radiation use efficiency is the percentage part of incident solar radiation spectrum being utilized by plants.
What is a Geiger counters used for?
It is used to measure radiation and is commonly used to detect objects that produce nuclear radiation.
What is used to measure radiation?
