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 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 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 the fraction of radiation a surface can reflect is called?
Reflection

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 an absorptance?
An absorptance is a ratio measuring absorbed radiation and incident radiation - to show how well a particular surface absorbs radiation.
What are the factors the determine a planets albedo?
Clouds can increase a planet's albedo asthey reflect the radiation
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 fraction of sunlight is reflected by a surface?
The answer varies from one surface to another. A highly polished mirror will reflect almost all whereas a rough black body will reflect very little.
How do you reflect radiation?
For IR, visible, and UV radiation; any shiny surface will do. For acoustic radiation, any massive smooth surface will do. For em radiation, any material with a very different dielectric constant from that of air will do. For ionizing radiation, there is a lot of money to be made from this discovery. That problem is yet (mainly) to be solved.
True or False On avereage clouds reflect more solar radiation back to space than the earths surface?
no
What gases such as co2 and water vapor absord the sun radiation and reflect it back to earth's surface?
Greenhouse gases.
Visible and shortwave radiation heat Earth?
Yes it is. Visible light or Shortwave are radiation and it contain energy, when these radiation hit earth surface some fraction of radiation is absorb and transform from radiation energy to thermal energy.
