Does the earth or the sun emit more infrared radiation?
The Earth emits more infrared radiation than the Sun. The Sun emits mostly visible light and ultraviolet radiation, while the Earth's surface absorbs this energy and reradiates it as infrared radiation due to its lower temperature.
Does the radiation emitted by earth's surface have longer or shorter wavelengths compared to solar radiation?
The radiation emitted by Earth's surface has longer wavelengths compared to solar radiation. Earth emits long-wave radiation in the infrared range, while solar radiation consists of shorter-wave radiation in the visible and ultraviolet ranges.
The albedo of the earth's surface is the fraction of solar radiation that is?
The albedo of the Earth's surface is the fraction of solar radiation that is reflected back into space. It is a measure of how reflective a surface is, with higher albedo values indicating more reflection and less absorption of sunlight by the surface. Land surfaces, ice, and clouds generally have higher albedo values, while oceans and forests have lower albedo values.
The Earth's surface absorbs more radiant energy from the sun than the atmosphere?
Yes, the Earth's surface absorbs about 50% of the Sun's incoming solar radiation, while the atmosphere absorbs about 20%. The absorbed energy is then re-emitted by the Earth's surface as infrared radiation.
How does energy produced in the core of the sun reach the surface how long?
Mainly by radiation - however, the radiation quickly gets absorbed by an atom, and re-emitted, so it takes quite a while to reach the surface. In the outer part of the Sun, the energy also gets transported through convection.
Which is the best absorber of inferared radiation heat a dull surface or a shiny one?
A dull surface is a better absorber of infrared radiation heat compared to a shiny surface. The rough texture of a dull surface allows for more absorption of infrared radiation, while a shiny surface reflects much of the radiation.
How does solar radiation reach the surface of the earth?
Solar radiation reaches the surface of the Earth through the process of electromagnetic radiation emitted by the Sun. This radiation travels through space and reaches Earth's atmosphere, where it penetrates and warms the surface of the planet. The atmosphere helps block harmful radiation while allowing sunlight to reach the surface.
What is the difference between a UV stabilizer and a UV absorber?
A UV stabilizer helps extend the lifespan of a material by preventing UV-induced degradation, while a UV absorber absorbs UV radiation and converts it into harmless heat, reducing the material's exposure to UV rays. Stabilizers work over the long term to maintain material integrity, while absorbers provide short-term protection by dissipating UV energy.
Describe experiments to investigate the factors on which absorption and emission of radiation depend?
One experiment could involve varying the material of the absorbing/emitting surface while keeping all other factors constant, to determine the effect of material type on absorption and emission. Another experiment could involve changing the temperature of the surface and observing how it affects the absorption and emission spectra. Additionally, one could vary the intensity or wavelength of the incoming radiation and measure the corresponding absorption and emission characteristics to study their dependence on these factors.
What Happens To Radiation When It Hits Eath's Surface?
When radiation hits Earth's surface, it can be absorbed, reflected, or scattered. Some of the absorbed radiation warms the surface, causing temperatures to increase, while some is re-radiated back into the atmosphere as heat. The remaining radiation is reflected back into space, contributing to Earth's energy balance.
What is the olitterence between insolation and terrestrial radiation?
Insolation refers to solar radiation received by the Earth's surface, while terrestrial radiation refers to the heat energy emitted by the Earth's surface back into the atmosphere. Insolation provides the energy input that drives the Earth's climate system, while terrestrial radiation plays a role in heat exchange processes like cooling at night.
Which parts of the Sun's radiation are responsible for heating Earth's surface?
The visible light and infrared radiation from the Sun are primarily responsible for heating Earth's surface. Visible light is absorbed by the Earth's surface, warming it up, while infrared radiation is absorbed by greenhouse gases in the atmosphere, trapping heat and contributing to the greenhouse effect.
What percent of the solar radiation that arrives at the top of the atmosphere is absorbed by the earth surface?
Approximately 70% of the solar radiation that arrives at the top of the Earth's atmosphere is absorbed by the Earth's surface, while the remaining portion is reflected back into space or absorbed by the atmosphere.
Is a toster a conduction convection or radiation?
A toaster uses primarily conduction and radiation to cook food. Conduction occurs when the heating elements directly heat the bread touching them, while radiation happens when the heat is emitted to cook the outer surface.
Who invented infrared radiation?
Matt Clarke created raidiation to kill betrayers
What percentage of the suns radiation is absorbed by the earths surface?
Roughly 70% of the sun's radiation is absorbed by the Earth's surface, while the remaining 30% is reflected back into space. This absorbed energy plays a crucial role in driving Earth's climate and weather patterns.
How does the energy produced in the sun reach the surface?
Mainly by radiation - however, the radiation quickly gets absorbed by an atom, and re-emitted, so it takes quite a while to reach the surface. In the outer part of the Sun, the energy also gets transported through convection.
