The photon is adsorbed in the first atom that it encounters. the atom then retains the energy for a finite period of time, and then ejects it as a photon, in the frequency of the atom. The larger the atom, the lower the freq. so, a lot of the re-raidation occurs in the IR band (heat) A good example of this, is the UV photons impinging on (or into) your skin. the result (not incliuding the celluar damage) will be felt as heat. and if continued long enough, a burn will result. Want More proof?, try a UV laser. Dr. B

What is the highest energy photon that can be absorbed by a ground-state hydrogen atom without causing ionization?
The highest energy photon that can be absorbed by a ground-state hydrogen atom without causing ionization is the photon energy equivalent to the ionization energy of hydrogen, which is approximately 13.6 electron volts. This is the energy required to completely remove the electron from the atom. Any photon with higher energy would cause ionization of the hydrogen atom.
What happens when a molecule combusts?
Combines with oxygen
In theory what happens to water at absolute zero should it constantly expand to this point?
At absolute zero, water would freeze and form a crystal lattice structure as its molecules slow down and lose kinetic energy. The expansion that occurs when water freezes is due to the arrangement of molecules in the crystal lattice, not necessarily related to temperature.
What happens to sunlight that hits earth's surface?
When sunlight hits Earth's surface, it can be absorbed, reflected, or scattered. Some of the sunlight is absorbed by the ground, causing it to heat up. The rest is reflected back into the atmosphere or scattered in different directions.
What happens when radiation reaches earth's surface?
When radiation reaches Earth's surface, it can be absorbed, reflected, or scattered. The amount of radiation that is absorbed can contribute to heating of the surface and atmosphere. This process is fundamental for maintaining Earth's energy balance and climate.
What does a photon do in the process of light absorption and emission?
A photon is a tiny particle of light that is absorbed by an atom or molecule during the process of light absorption. This absorption causes the atom or molecule to become excited, leading to the emission of a new photon when the atom or molecule returns to its original state.
What happens when carbon dioxide absorbs an IR photon?
The molecule vibrate
What physically happens to a molecule when it absorbs a photon?
When a molecule absorbs a photon, its energy increases and the electrons in the molecule are excited to higher energy levels. This can lead to changes in the molecular structure or bond vibrations. In some cases, the molecule may undergo a chemical reaction or emit a photon in a process known as fluorescence or phosphorescence.
What happens when a photon is absorbed by a material or object?
When a photon is absorbed by a material or object, its energy is transferred to the material, causing its atoms or molecules to become excited. This can lead to various effects such as heating, the emission of light, or triggering chemical reactions.
What happens to a photon when it hits a leaf?
When a photon hits a leaf, it may be absorbed by chlorophyll molecules, which are specialized pigments that can capture the energy of the photon and initiate photosynthesis. This absorbed energy is then used to drive chemical reactions that convert carbon dioxide and water into glucose and oxygen.
How are photons absorbed by materials and what happens to them afterwards?
Photons are absorbed by materials when their energy matches the energy levels of electrons in the material. When a photon is absorbed, it can cause an electron to move to a higher energy level or be released as heat. The absorbed energy can also be re-emitted as a new photon or used to create a chemical reaction.
Can you explain why an electron's energy increases when it absorbs a photon and also describe what happens to the photon in this process?
When an electron absorbs a photon, its energy increases because the photon transfers its energy to the electron. The photon ceases to exist as a discrete particle and its energy is absorbed by the electron, causing it to move to a higher energy level.
WHAT HAPPENS IN THE PHOTOSYSTEM 2 protein when it is hit by a photon of light?
In photosystem II, the photon of light is absorbed by a pigment molecule, which causes an electron to become excited. This electron is then passed through a series of electron carrier molecules, creating a flow of electrons used to generate ATP and NADPH during the light-dependent reactions of photosynthesis.
Why is glass transparent?
When the electrons in molecules are unable to absorb the energy of incident photon, the photon continues along its path. This happens in the case of glass, even though glass is not 100 percent transparent, as some of the photon energy is absorbed by the glass electrons.
How can a photon be destroyed or created?
A photon can be created when an electron transitions to a lower energy level and emits a photon. Conversely, a photon can be absorbed and "destroyed" when it is absorbed by an electron, causing the electron to transition to a higher energy level.
An electron gains 5.5 x 10-16 J of energy when a photon is absorbed What is the frequency of the photon that is absorbed?
8.3 x 1017 Hz
What happens when a photon hits a chlorophyll molecule?
When a photon hits a chlorophyll molecule, it excites an electron within the molecule to a higher energy state. This energized electron is then passed along a chain of molecules in the photosystem to eventually drive the process of photosynthesis, converting light energy into chemical energy.
