How does long wavelength radiation contribute to the greenhouse effect?
Long wavelength radiation, such as infrared radiation, is emitted by Earth's surface after absorbing solar radiation. Greenhouse gases in the atmosphere trap this long wavelength radiation, leading to a warming effect known as the greenhouse effect. This process helps regulate Earth's temperature by keeping the planet warm enough to support life.
Why does the Earth emit longer wave radiation than the Sun?
The Earth emits longer wavelength infrared radiation because it absorbs sunlight and re-radiates it as heat. The Sun, on the other hand, emits shorter wavelength radiation in the form of visible light because it is much hotter than the Earth.
The primary wavelenght of radiation emitted by earths surface are?
The primary wavelength of radiation emitted by Earth's surface is in the thermal infrared range, typically around 10 micrometers (μm). This is known as long-wave radiation, which the Earth emits as heat energy.
What happens to th radiation as it passes through earth atmosphere?
As radiation passes through Earth's atmosphere, some of it is absorbed and scattered by gases and particles. This can result in attenuation of the radiation, meaning that its intensity decreases. Different types of radiation are affected in various ways based on their energy and wavelength.
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.
Clouds absorb outgoing radiation emitted by earth and reradiated a portion of it back to the surface?
Clouds play a crucial role in the Earth's energy balance by absorbing outgoing infrared radiation emitted from the surface. This absorbed energy is then reradiated back toward the Earth, which helps to warm the atmosphere and surface. This process contributes to the greenhouse effect, ultimately influencing climate and weather patterns. Additionally, the presence of clouds can affect the amount of solar radiation that reaches the Earth's surface, further impacting temperatures.
What absorbed energy is reradiated some of which escapes into space?
The absorbed energy that is reradiated, some of which escapes into space, primarily refers to the Earth's thermal radiation. When the Earth absorbs sunlight, it warms up and subsequently emits infrared radiation. This process helps regulate the planet's temperature, but not all of this emitted energy remains trapped; a portion escapes into space, contributing to the balance of energy between the Earth and its atmosphere. This energy exchange is crucial for maintaining the Earth's climate system.
Which part does reach earth - longer wavelength infrared or shorter wavelength infrared?
Longer wavelength infrared radiation reaches Earth. This type of infrared radiation is also known as thermal infrared, which is emitted by the Earth's surface and is an important component of the Earth's energy budget. Shorter wavelength infrared, such as near-infrared, is mostly absorbed by the atmosphere and does not reach the surface.
How does long wavelength radiation contribute to the greenhouse effect?
Long wavelength radiation, such as infrared radiation, is emitted by Earth's surface after absorbing solar radiation. Greenhouse gases in the atmosphere trap this long wavelength radiation, leading to a warming effect known as the greenhouse effect. This process helps regulate Earth's temperature by keeping the planet warm enough to support life.
What size wavelength carries the greatest amount of energy on earth?
Short-wavelength radiation, such as gamma rays and X-rays, carry the greatest amount of energy on Earth. These wavelengths have higher frequency and shorter wavelengths compared to longer-wavelength radiation like visible light or radio waves.
Why does the Earth emit longer wave radiation than the Sun?
The Earth emits longer wavelength infrared radiation because it absorbs sunlight and re-radiates it as heat. The Sun, on the other hand, emits shorter wavelength radiation in the form of visible light because it is much hotter than the Earth.
How much of the suns reflected energy is reradiated back into space?
Approximately 30% of the Sun's energy that reaches Earth is reflected back into space by clouds, atmospheric particles, and Earth's surface. This reflected energy is known as the albedo effect. The remaining energy is absorbed by the Earth, warming the planet and driving various processes, such as weather and climate. Ultimately, a portion of the absorbed energy is reradiated back into space as infrared radiation.
How does ultraviolet radiation harm hgumans and life on earth?
The UV radiation harms life and humans on earth. These UV radiations are high wavelength. They cause skin cancer like problems.
Which type of radiation from the sun is the longest wavelength?
Radio waves are at the long wavelength end of the sun's emissions.
Is it true that the wave length of energy radiated from the earth back into the atmosphere is longer than the incoming solar radiation?
Yes, it is true. The energy radiated from the Earth back into the atmosphere is primarily in the form of infrared radiation, which has a longer wavelength compared to the incoming solar radiation, which is predominantly in the visible spectrum and has shorter wavelengths. This difference in wavelength is due to the Earth's surface temperature being much lower than that of the Sun. As a result, while solar radiation peaks in the visible range, Earth's emitted radiation peaks in the infrared range.
What best describes the primary wavelength of radiation emitted by Earth's surface?
they are longer than those emitted by the sun.
To scatter a beam of radiation a particle must be smaller in size than the wavelength of the radiation involved?
Yes, scattering of radiation occurs when the size of the particle is smaller than the wavelength of the radiation. This phenomenon causes the radiation to interact with the particles, changing its direction and intensity. This principle is commonly observed in processes like Rayleigh scattering in the Earth's atmosphere.
