It is called an equivalent fraction.
It is called a decimal fraction.
It is called "writing a fraction as an equivalent fraction with a larger denominator"!
A unit fraction.
It is called a [decimal] fraction.
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.
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 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.
The fraction of total radiation reflected by a surface is known as its albedo. It is expressed as a value between 0 and 1, with higher values indicating greater reflectivity and lower values indicating lower reflectivity.
The reflectivity of a surface is called its albedo. It is a measure of how much of the incoming radiation that hits a surface is reflected back without being absorbed. High-albedo surfaces reflect more light, while low-albedo surfaces absorb more 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.
That process is called reflection. Radiation can bounce off the surface of an object, changing direction but maintaining its energy.
The interaction of light beams with a surface is called regular reflection when the light beams reflect off all points of the surface at the same angle. When the light beams hit the surface and reflect off in different angles it is called diffuse reflection.
Light rays reflect in many directions on a rough surface due to the uneven nature of the surface, which causes the rays to scatter in various directions rather than reflect uniformly as with a smooth surface.
The radiation from the sun that provides heat is called infrared radiation. This type of radiation is responsible for warming the Earth's surface and is part of the electromagnetic spectrum.
The term for solar radiation that reaches the earth's surface is "insolation." Insolation is the amount of solar radiation received per unit area at the surface of the Earth.
The interaction of light beams with a surface is called regular reflection when the light beams reflect off all points of the surface at the same angle. When the light beams hit the surface and reflect off in different angles it is called diffuse reflection.
