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.
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.
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.

A number can be called either a mixed number or a mixed fraction when it is a whole number with a fraction.
It is called a mixed number or a mixed fraction.
albedo
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.
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.
Reflection
This is called the "albedo." It is the ratio of reflected light compared to incident light, and depends on the surface material and its condition (e.g. snow, grassland).
One term often used in Astronomy is the albedo. It refers to the percentage or fraction of incoming light that is reflected.

A ray of light which strikes the surface is called incident ray and a surface which is reflected is called a reflected ray
25% is absorbed by clouds.25% is reflected by clouds.45% is absorbed by the earth's surface.5% is reflected by the earth's surface.So 50% reaches the surface of the earth (But 5% of that is reflected).
That light is called infared radiation =)
At the earth's surface about 51% of incoming solar radiation is absorbed, and 4% is reflected back into space.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%
