What is meant by diffuse radiation?
Diffuse radiation is solar radiation reaching earth’s surface after having been scattered from the direct solar beam by molecules or suspensoids in the atmosphere.
What is diffuse solar radiation Mcq?
Explanation: Diffuse radiation received from the sun after its direction has been changed by reflection and scattering by the atmosphere. Since the solar radiation is scattered in all direction in the atmosphere, diffuse radiation comes to the earth from all parts of the sky.
What is total radiation?
(Global radiation) [Integral radiation] Radiation corresponding to the entire frequency (wavelength) spectrum from zero to infinity. Sometimes total radiation means radiation corresponding to a finite frequency (wavelength) range. …
What is beam and diffuse radiation?
Beam radiation is the solar radiation received from the Sun without having been scattered by the atmosphere. Diffuse radiation is that received from the Sun after its direction has been changed by scattering by the atmosphere.
What is diffused solar radiation?
1. The total amount of solar energy received by a horizontal surface from all parts of the sky apart from the direct sun.
What does solar radiation include?
All of the energy from the Sun that reaches the Earth arrives as solar radiation, part of a large collection of energy called the electromagnetic radiation spectrum. Solar radiation includes visible light, ultraviolet light, infrared, radio waves, X-rays, and gamma rays.
What is diffuse in science?
Diffusion is the process of movement of molecules under a concentration gradient. The molecules move from a region of higher concentration to a region of lower concentration until the concentration becomes equal throughout. Liquid and gases undergo diffusion as the molecules are able to move randomly.
What is diffuse mean in medical term?
Medical definitions for diffuse Not limited to one tissue or location; widespread. To spread or to be spread widely, as through a tissue.
What is the difference between beam and diffuse radiation?
5.5). Beam radiation is the solar radiation received from the Sun without having been scattered by the atmosphere. Diffuse radiation is that received from the Sun after its direction has been changed by scattering by the atmosphere.
How does diffuse sky radiation reach the Earth?
Diffuse sky radiation is solar radiation reaching the Earth’s surface after having been scattered from the direct solar beam by molecules or particulates in the atmosphere.
What is the difference between direct and diffuse irradiance?
The short-wave fluxes, also called solar fluxes, are separated into direct and diffuse irradiance. The direct irradiance is the nonscattered flux, while the diffuse irradiance is the scattered radiative flux from the sun. The direct irradiance is sometimes further separated into visible and near-infrared components.
Why is radiation said to be isotropic or diffuse?
1 cosﾎｸ) stems from the existence of surfaces for which, to a good approximation, I ﾎｻ,eis independent of direction. Such surfaces are termed diffuse, and the radiation is said to be isotropic. 窶｢窶ｯ the projected areais how dA
