Is absorbed radiation re emitted as energy?
Yes, absorbed radiation can be re-emitted as energy in the form of electromagnetic radiation or heat. This phenomenon is known as re-emission or re-radiation. The amount and wavelength of the re-emitted radiation depend on the properties of the absorbing material.
What Radiation emitted by a body that absorbed it first?
The radiation emitted by a body that absorbed it first is known as re-emitted or secondary radiation. This occurs when absorbed energy is re-radiated by the object in a different form such as heat or light.
What is re-radiation mean?
Re-radiation refers to the process by which absorbed radiation is emitted or reflected back into the surrounding environment in the form of electromagnetic waves. This phenomenon occurs in various natural and man-made systems, including antennas, satellites, and objects exposed to sunlight. Re-radiation plays a crucial role in the propagation and transfer of energy in these systems.
What is counter radiation?
Counter radiation is the emission of radiation by a material in response to being exposed to external radiation. This phenomenon involves the material absorbing incoming radiation and then re-emitting it in a different form. Counter radiation can influence the overall heat transfer mechanisms in a system.
What causes fluorescence?
Fluorescence occurs when a molecule absorbs light energy and then quickly releases it as lower-energy, longer-wavelength light. This phenomenon is typically caused by specific chemical structures within a molecule that allow it to absorb light and emit fluorescence.

What happens when a star becomes a black dwarf?
Then it will not emit any more radiation - except that it will eventually re-emit any radiation it receives, especially the cosmic background radiation.Then it will not emit any more radiation - except that it will eventually re-emit any radiation it receives, especially the cosmic background radiation.Then it will not emit any more radiation - except that it will eventually re-emit any radiation it receives, especially the cosmic background radiation.Then it will not emit any more radiation - except that it will eventually re-emit any radiation it receives, especially the cosmic background 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.
Is the earths radiation shortwave or longwave?
Earth's radiation is primarily longwave. Shortwave radiation from the sun enters the Earth's atmosphere, where some is absorbed and re-radiated as longwave radiation. This longwave radiation is what is emitted back out into space.
What is re-radiation mean?

What type of radiation from Earth is the long-wave radiation absorbed by greenhouse gases?
The long-wave radiation absorbed by greenhouse gases is primarily in the form of infrared radiation. After the Earth's surface absorbs solar energy, it re-emits this energy as infrared radiation, which has longer wavelengths compared to the short-wave radiation from the sun. Greenhouse gases in the atmosphere, such as carbon dioxide and methane, absorb and re-radiate this infrared radiation, contributing to the greenhouse effect and warming the planet.
What causes fluorescence?
Fluorescence occurs when a molecule absorbs light energy and then quickly releases it as lower-energy, longer-wavelength light. This phenomenon is typically caused by specific chemical structures within a molecule that allow it to absorb light and emit fluorescence.
Carbon dioxide traps shortwave radiation and re-radiates it?
Carbon dioxide mainly has an effect on longwave radiation. It absorbs longwave radiation and re-radiates it, some of it back downwards. This means carbon dioxide increases the amount of radiation going back down to the surface, and the surface has to warm up to compensate.
What happens to incoming solar radiation after it is reflected off the surface of the earth?
Incoming solar radiation that is reflected off the surface of the Earth can be absorbed by atmospheric gases, clouds, or particles in the air. Some of this radiation can be scattered or absorbed by the atmosphere and re-emitted as infrared radiation. This process helps regulate the Earth's temperature and maintain the energy balance of the planet.
What type of radiation is trapped on the Earth's surface by the Greenhouse effect?
Infrared radiation is the type of radiation that gets trapped on Earth's surface by the greenhouse effect. This radiation is emitted by the Earth's surface in response to the incoming solar radiation and is absorbed and re-emitted by greenhouse gases in the atmosphere, leading to the warming of the planet.
