The answer depends on what the question is about. Some possible valid questions concern the fraction of solar radiation which:
- falls on the earth (as opposed to going in other directions)
- is blocked by the earth's magnetic field
- is blocked by the ozone layer
- is reflected by clouds
- is absorbed by the atmosphere
- is reflected by the surface
- is absorbed by the surface
- is useful to plants
- is in wavelengths shorter than ultra violet (UV)
- is in the UV range
- is in the visible range
- is in the infra red (IR) range
- is in wavelengths longer than IR.

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 the total radiation?
If you are given the "the total radiation" (e.g. 100 rads of radiation) and you are given another radiation level (e.g. 75 rads of radiation) and then you are asked: 'What is "the fraction of the total radiation?"', then you would answer "75/100".
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 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.
Is 0.1a equelivent fraction?
Every fraction is an equivalent fraction: each fraction in decimal form has an equivalent rational fraction as well as an equivalent percentage fraction.
