Which substance present in the atmosphere is responsible for the absorption of solar radiation with a wavelength less than 242 nm?
Oxygen is responsible for the absorption of solar radiation with a wavelength less than 242nm. UV radiation splits oxygen into atoms and the atoms combine with other oxygen molecules to form ozone. Generally, all multi-atom?æ compounds are capable of absorbing UV radiation when the wavelength is short.

How do greenhouse gases absorb infrared radiation and contribute to the Earth's warming?
Greenhouse gases in the Earth's atmosphere absorb infrared radiation emitted by the Earth's surface. This absorption traps heat in the atmosphere, leading to the warming of the Earth's surface. This process is known as the greenhouse effect.
What is the definition of lambda max for a particle absorbing in the uv region?
Lambda max (λ max) is the wavelength at which a particle absorbs light most strongly in the ultraviolet (UV) region. It represents the peak absorbance of the particle's specific UV absorption spectrum.
Because c the speed of electromagnetic radiation is a constant the wavelength of the radiation is....?
... inversely proportional to its frequency. This means that as the frequency of radiation increases, its wavelength decreases, and vice versa. This relationship is expressed by the equation λ = c / f, where λ is the wavelength, c is the speed of light, and f is the frequency of the radiation.
Which component of the biosphere contains oxygen that you breathe as well as oxygen that protects us from radiation?
The atmosphere in the biosphere contains the oxygen that we breathe. The ozone layer, also part of the atmosphere, is responsible for protecting us from harmful radiation from the sun by absorbing most of the sun's ultraviolet radiation.
Where is over 95 percent of incoming ultraviolet radiation absorbed?
Over 95 percent of incoming ultraviolet radiation is absorbed by the ozone layer in the stratosphere of the Earth's atmosphere. This absorption helps protect life on Earth by preventing most harmful UV radiation from reaching the surface.
Which two layers of the atmosphere are responsible for the majority of the solar radiation absorption?
Stratosphere and Thermosphere
What is an absorption line?
An absorption line is a line which corresponds to the absorption of electromagnetic radiation at a specific wavelength.
Which two layers of the atmosphere are responsible for the majority of solar radiation absorption?
The troposphere and stratosphere are responsible for the majority of solar radiation absorption in the atmosphere. The troposphere absorbs most of the incoming solar energy through the greenhouse effect, while the stratosphere absorbs ultraviolet radiation from the sun through the ozone layer.
What wavelengths of radiation from the sun does the upper atmosphere absorb?
The upper atmosphere absorbs harmful ultraviolet (UV) radiation from the sun. This absorption occurs mainly in the ozone layer, which absorbs UVB and UVC wavelengths. Absorption of these wavelengths protects life on Earth from the damaging effects of excessive UV radiation.
What is responsible for absorbing the largest portion of incoming solar radiation?
The Earth's surface absorbs the largest portion of incoming solar radiation. This absorption heats the surface, causing it to emit infrared radiation back into the atmosphere.
What are 3 types of ultra violet radiation?
The three types of ultraviolet radiation are UVA, UVB, and UVC. UVA has the longest wavelength and is associated with skin aging. UVB has a medium wavelength and is responsible for sunburn and skin cancer. UVC has the shortest wavelength and is mostly absorbed by the ozone layer in the atmosphere.
Ways that ozone is removed from the atmosphere?
CFC gases which are pollutants are responsible for the depletion of ozone layer. CFC convert ozone to oxygen and make it useless for the absorption of UV radiation.
What causes electromagnetic radiation to change its wavelengths?
Electromagnetic radiation changes its wavelengths when it interacts with matter due to phenomenon such as absorption, reflection, or scattering. These interactions can cause the radiation to lose or gain energy, resulting in a shift in wavelength.
How radiation from the sun penetrates the atmosphere by heating the air?
Solar radiation penetrates most of the atmosphere and is mostly absorbed by earth's surface. The surface then radiates energy of a different wavelength (in the thermal infrared part of the spectrum, which we perceive as heat) back to the atmosphere, heating the lower atmosphere.
The amount of ultraviolet radiation hitting the Earth's surface is greatly reduced by which gas in the atmosphere?
Ozone is the gas in the atmosphere that greatly reduces the amount of ultraviolet radiation hitting the Earth's surface. The ozone layer acts as a shield, absorbing most of the harmful UV radiation before it reaches the surface.
Why is Earth's atmosphere mainly heated from the ground up?
Solar radiation mostly passes through the atmosphere without heating it, due to its wavelength. It does not pass through the ground, however, and it heats the ground. The ground emits radiation at a wavelength dependent on its temperature. This radiation happens to be in the thermal infrared part of the spectrum, or in other words, sensible heat. Therefore, the atmosphere is heated by the surface, whereupon the heat tends to rise and heat the lower atmosphere.
What does fluoresce mean?
Fluoresce means to emit light or glow when exposed to ultraviolet radiation or certain wavelengths of light. This phenomenon is commonly seen in certain substances like fluorescent markers, minerals, or biological materials.
