Radiation is a general term for the energy transmitted through space.
Incident radiation is a term used when referring to the radiation hitting a specific surface. For instance, the incident radiation for a solar panel is the total amount of radiation hitting the surface of the solar panel. This is in contrast to direct beam radiation which refers to only that radiation which arrives in a strait line from the sun. (It differs in that total incident radiation includes additionally the component of diffuse radiation.)

Why Raman intensity is measured in arbitrary units?
because thee is no proper intensity of incident radiation and there is cotinuously changing the intensity of incident radiation. ofcourse there is one colour at one time but at next time the light of next colour is allow to fall on the sample may by monochromator. (UOG students)
Why is it cold at the poles?
The answer to this question involves the angle at which solar radiation is intercepted by the earth's atmosphere. The rule is that if solar radiation is incident perpendicular to the atmosphere the solar radiation that is incident on the earth's surface will be greatest. Incoming solar radiation at the poles comes in at a sharper angle and is spread over a greater surface area of atmosphere than at the equator. In this way, the poles have more of an atmospheric filter and experience less radiation per area time and hence have lower average temperatures.
Name the north south latitude that receives least sunrays?
-- The north latitude that receives the least total incident solar radiation on the average over a year is 90° North. That's the location of the north pole. -- The south latitude that receives the least total incident solar radiation on the average over a year is 90° South. That's the location of the south pole.
How does distance from the sun affect a planet's climate?
Generally speaking, the greater distance from the Sun means a colder climate, due to the decreased incident solar radiation.
How does radiant energy convert into electricity?
This can be accomplished in a few different ways, but the most common is to use the heat differential created by radiant energy to heat a surface, while a more temperature-resistant surface is bonded to it thus causing an electron flow. ( This is now a different person ) Well, I know a way to convert radiant energy into electricity. Photovoltaic cells! In other words photovoltaic cells are just solar panels! They convert radiant energy into electricity.
What is an absorptance?
An absorptance is a ratio measuring absorbed radiation and incident radiation - to show how well a particular surface absorbs radiation.
How does the greenhouse effect work relative to earth's energy balance?
The balance of incident Solar radiation as compared to the Re-Radiation of the same incident Solar radiation is skewed so that the Re-Radiation is cancelled and the Heat - easily in infra-red form - is Retained at and by the Earth.
What is the definition of radiation use efficiency and light use efficiency?
radiation use efficiency is the percentage part of incident solar radiation spectrum being utilized by plants.
Does black absorb or reflect?
Black absorbs radiation. A perfectly black body would absorb all the radiation that is incident upon it.
Most of the radiation incident upon the Earth falls within the?
the shortwave spectrum
What is difference between emitted radiation heat and reflected radiation heat?
The magnitude of the incident angle with the normal of the reflection surface and reflection angle with the normal of the surface are the same. The direction of the reflection is away form the surface and the incident is toward the surface.
Definition of fluorescence?
The visible or invisible radiation emitted by certain substances as a result of incident radiation of a shorter wavelength such as X-rays or ultraviolet light.
What is a perfect black body?
A perfect blackbody absorbs all radiation incident on it and It emits electromagnetic radiation in the form of thermal radiation from its surface. OR A perfect blackbody is a perfect emitter and perfect absorber.
What is causing atmospheric circulation on Earth?
The Earthly Incident Radiation from the Sun is almost exclusively responsible for this.
Greenhouse effect events in order starting with lights origin?
Incident infrared radiation is blocked. Visible and ultraviolet radiation heat Earth. Earth radiates infrared radiation. Infrared radiation is blocked and heats Earth. Visible and shortwave radiation heat Earth.Earth radiates longwave radiationLongwave radiation is reflected downward Longwave radiation heats Earth
What is the difference between reflectivity and reflectence?
reflectivity is the fraction of incident radiation reflected by a surface. In general it must be treated as a directional property that is a function of the reflected direction, the incident direction, and the incident wavelength. However it is also commonly averaged over the reflected hemisphere to give the hemispherical spectral reflectivity:reflectance a measure of the ability of a surface to reflect light or other electromagnetic radiation, equal to the ratio of the reflected flux to the incident flux.
What does A higher albedo mean?
A higher albedo means that more of the incident radiation is reflected, and less of it is absorbed.
