What Wavelengths Of Radiation Produce The Greenhouse Effect?

The greenhouse effect is a process where heat is trapped near Earth’s surface by greenhouse gases, which act as a cozy blanket enveloping the planet. The main source of heat to the Earth is electromagnetic radiation at most wavelengths passing through the Earth’s atmosphere. Short wavelength radiation from the Sun passes through Earth’s atmosphere, but long waves don’t so easily. At long wavelengths, our air acts like a wall that traps some of the infrared radiation.

The greenhouse effect occurs because the atmosphere is relatively transparent to solar radiation wavelengths, while it absorbs infrared radiation. Carbon dioxide, a good absorber of wavelengths falling in the infrared radiation region of the spectrum, absorbs energy with a wavelength of 15 μm (micrometers). This makes carbon dioxide a good absorber of wavelengths falling in the infrared radiation region of the spectrum.

The greenhouse effect is a consequence of interactions between electromagnetic radiation and matter, where photons are absorbed. Different substances in the atmosphere may absorb, transmit, or reflect electromagnetic waves in different ways, depending on the wavelengths of the radiation. A greenhouse gas is called because it absorbs infrared radiation in the form of heat, which is circulated in the atmosphere and eventually lost to space. In short, the absorption of infrared radiation by greenhouse gases contributes to an increase in the temperature of the Earth’s surface and the atmosphere.

Ozone absorbs nearly 100 ultraviolet rays, carbon dioxide absorbs radiation with wavelengths between 1.5 – 30 µm, and water absorbs radiation with wavelengths between 1.5-30 µm.

What causes the greenhouse effect radiation?

The greenhouse effect occurs when greenhouse gases, such as methane, carbon dioxide, nitrous oxide, and water vapor, absorb and re-radiate infrared radiation, causing the Earth’s surface to heat up. This process occurs when sunlight passes through the atmosphere and reaches Earth’s surface, either reflected or absorbed. Reflected sunlight doesn’t add heat to the Earth system, as it bounces back into space. However, absorbed sunlight increases Earth’s surface temperature, causing it to re-radiate as long-wave radiation, which is invisible to the eye but feels as heat.

Without greenhouse gases, most long-wave radiation from Earth’s surface is absorbed and re-radiated multiple times before returning to space. Heat re-radiated downward towards Earth is absorbed by the surface and re-radiated again.

How does long wavelength radiation contribute to the greenhouse effect?

The Greenhouse Effect is a phenomenon where greenhouse gases absorb and re-radiate Earth’s long-wavelength radiation, keeping Earth’s temperature warm enough for human life. Without these gases, Earth’s climate would be 33˚ C colder, mostly frozen, and uninhabitable. The recent concern about greenhouse warming is based on abnormal levels of greenhouse gases leading to unprecedented climate changes in human history.

What radiation is the greenhouse effect due to?

The correct answer is IR rays, which are responsible for the greenhouse effect, which occurs when infrared radiation from the Sun is absorbed by water vapor and certain gases in the atmosphere, increasing Earth’s temperature. The MP Police Constable 2023 PET Admit Card has been released, and the second phase of selection examination will be conducted from 23. 09. 2024 to 09. 11. 2024. The Madhya Pradesh Professional Examination Board (MPPEB) announced the MP Police Constable Vacancy 2023 on June 23, 2023.

What is the greenhouse effect in terms of the wavelength of radiation and its interaction with matter?

The greenhouse effect is a phenomenon that increases Earth’s temperature by releasing greenhouse gases into the atmosphere. These gases, which can be short or long wavelength, absorb and re-radiate long wavelength radiation. Greenhouse gases absorb long wavelength radiation, which they do not absorb short wavelength radiation. This long wavelength radiation, which is thermal, is then radiated towards the Earth, increasing its temperature. This process is influenced by specific human activities that increase greenhouse gases. Therefore, the greenhouse effect is a significant global issue that requires urgent attention and action.

What is the greenhouse effect of long wave and short wave radiation?

The Earth’s atmosphere absorbs short-wave radiation from the Sun, which heats its surface, and long-wave radiation, which is released by the Earth’s surface, traps this heat by producing greenhouse gases like methane, carbon dioxide, and nitrous oxide. Human activities like burning fossil fuels, deforestation, landfill waste, and agriculture contribute to the increase in greenhouse gases in the atmosphere. These activities release carbon dioxide, methane, and nitrogen oxides, which contribute to climate change and contribute to the greenhouse effect.

What wavelengths are absorbed by greenhouse gases?

Infrared radiation is a crucial part of the Earth’s climate, absorbing a wide spectrum of wavelengths. Water vapor and carbon dioxide can absorb wavelengths from 4 μm to 80 μm, while ozone can absorb wavelengths between 9 μm and 10 μm. Ozone is found in low concentrations, but strongly absorbs the sun’s ultraviolet wavelengths. The Greenhouse Effect occurs when the sun’s visible wavelengths pass through the atmosphere and reach Earth. About 51 percent of this sunlight is absorbed by land, water, and vegetation, while some energy is emitted back as infrared radiation.

Trace gases in the Earth’s atmosphere absorb longer wavelengths of outgoing infrared radiation, emitting infrared radiation in all directions. This process creates a second source of radiation to warm Earth, creating the natural greenhouse effect, which keeps Earth’s average global temperature at approximately 15°C (59°F).

What wavelength causes greenhouse effect?

Carbon dioxide (CO2) is a significant greenhouse gas with a long lifetime in Earth’s atmosphere, absorbing energy with a 15 μm wavelength. It moves into and out of the atmosphere through four major processes: photosynthesis, respiration, organic decomposition, and combustion. Methane, 30 times stronger than CO2, is 30 times stronger as an absorber of infrared radiation but is present in smaller concentrations and has a short-lived lifespan of approximately 8 years.

Methane is produced when bacteria decompose organic plant and animal matter in wetlands, sewage treatment plants, landfills, and cattle and termite guts. Scientists are concerned about increasing methane concentrations in regions where Arctic and alpine permafrost is thawing and releasing methane as it warms.

What do greenhouse gases do in terms of radiation?

Greenhouse gases absorb infrared radiation from the Sun, causing heat to be circulated in the atmosphere and eventually lost to space. They also increase the rate at which the atmosphere can absorb short-wave radiation from the Sun, but this has a weaker effect on global temperatures. The CO2 released from fossil fuel burning accumulates as an insulating blanket around Earth, trapping more Sun’s heat in the atmosphere. Human anthropogenic actions contribute to the enhanced greenhouse effect. The contribution of a greenhouse gas depends on its heat absorption, re-radiation, and presence in the atmosphere.

What is the main causes of greenhouse effect?

Greenhouse gases, including carbon dioxide, methane, nitrous oxide, and water vapor, trap heat in the atmosphere and contribute to global warming. Natural compounds and synthetic fluorinated gases also play a role. These gases have different chemical properties and are removed from the atmosphere through various processes. Carbon dioxide is absorbed by carbon sinks like forests, soil, and the ocean, while fluorinated gases are destroyed by sunlight in the upper atmosphere.

The influence of a greenhouse gas on global warming depends on three factors: its presence in the atmosphere (measured in parts per million, parts per billion, or parts per trillion), its lifetime (measured in ppm), and its effectiveness in trapping heat (measured in GWP), which is the total energy a gas absorbs over time relative to the emissions of 1 ton of carbon dioxide.

What is the wavelength of the greenhouse gas effect?

Earth’s surface emits longwave radiation with wavelengths ranging from 4 to 100 microns, which absorbs greenhouse gases that were largely transparent to solar radiation. The atmosphere near the Earth’s surface is mostly opaque to longwave radiation, with most heat loss occurring through evaporation and convection. However, radiative energy losses become more significant due to the decreasing concentration of water vapor, a key greenhouse gas.

Longwave radiation headed to space is emitted by a layer in the mid-troposphere, which is coupled to the surface by a lapse rate. This difference in temperature explains the difference between surface emissions and emissions to space, thereby explaining the greenhouse effect.

How is the greenhouse effect created?

The greenhouse effect is a phenomenon where Earth’s atmosphere traps the Sun’s heat, causing it to become warmer than it would be without an atmosphere. This process is a key factor in making Earth a comfortable place to live. Greenhouses, which are buildings with glass walls and roofs, are used to grow plants like tomatoes and tropical flowers. The greenhouse effect is a result of the presence of greenhouse gases in Earth’s atmosphere, which traps the Sun’s heat, resulting in a warmer Earth. This process is essential for maintaining Earth’s temperature and promoting its overall health.
