What is the fraction of solar radiation that is reflected off a particular surface called?

There is no particular term. This is because the reflectivity of a surface varies across the electromagnetic spectrum so a surface which reflects a large proportion of blue wavelengths in sunlight may or may not reflect a similar proportion of red wavelengths.

What is the fraction if solar radiation that is reflect off a particular surface called?
There is no special name. The fraction of sunlight which is reflected will be different from the fraction of other light. The reflectivity of a surface varies with the wavelength of the incident light.
What is the fraction of total radiation that is reflected by any surface called?
It is the reflectivity of the surface. However, it is important to note that the reflected fraction depends on the wavelength of the incident light.
What happens to the greatest common factor of the cylinders' surface area if its radius is squared?
Nothing. The cylinder's surface area does not have a GCF.
How do you find the surface area of a figure to the nearest square unit?
This is two problems. Surface area is measured in square units. The formulas for the area of different figures vary with the figures. The area of a regular four-sided figure is the length times the width. To round a number to a particular digit, look at the digit immediately to the right of your target, in this case, tenths of square units. If that digit is 4 or lower, zero it and everything to the right of it out. If that digit is 5 or higher, increase the target digit by one and zero everything to the right of it out. If your target digit is a 9, increasing it will turn it to zero and increase the digit to the left of it by one.
What percent of the earth's surface is covered by people?
The Earth's surface is covered by human 99%. add. the above seems not to consider the significant desert areas in the major continents (except Europe!), and Antarctica.
What is the fraction if solar radiation that is reflect off a particular surface called?
There is no special name. The fraction of sunlight which is reflected will be different from the fraction of other light. The reflectivity of a surface varies with the wavelength of the incident light.
The albedo of the earth's surface is the fraction of solar radiation that is?
reflected.
What is the fraction of the total radiation encountered that is reflected by a surface called?
albedo
What is the fraction of total radiation that is reflected by any surface called?
It is the reflectivity of the surface. However, it is important to note that the reflected fraction depends on the wavelength of the incident light.
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.
How much solar energy is reflected by the atmosphere and earth's surface?
About 6% of incoming solar radiation is reflected back into space from the atmosphere and 4% by the surface of the earth.Incoming solar radiation: 100%Reflected by the atmosphere: 6% : Absorbed by the atmosphere: 16%Continuing incoming solar radiation: 78%Reflected by clouds: 20% : Absorbed by clouds: 3%Continuing incoming solar radiation: 55%Reflected by the earth's surface: 4% : Absorbed by the earth's surface (lands and oceans): 51%
What is the correct definition of albedo?
The fraction of incident radiation reflected by a surface. -ie, how brightly something reflects a light. -usually referring to stars etc.
Solar radiation that is not reflected is absorbed by what?
Solar radiation that is not reflected is absorbed by clouds, the atmosphere and the surface of the earth.Incoming solar radiation: 100%Reflected by the atmosphere: 6% : Absorbed by the atmosphere: 16%Continuing incoming solar radiation: 78%Reflected by clouds: 20% : Absorbed by clouds: 3%Continuing incoming solar radiation: 55%Reflected by the earth's surface: 4% : Absorbed by the earth's surface (lands and oceans): 51%Source: (NASA)
What fraction of solar radiation reflected by a surface is called?
this question needs to be stated more precisely. The solar fraction is a measurement of usage of the solar thermal energy by the solar thermal system installed.
What happens when radiation reaches earth's surface?
90% of radiation reaching the surface of the earth is absorbed! and 10% is reflected into space.
About 6 percent of solar radiation is what by the Earth's surface?
Reflected.
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.
