What happen if a small energy photon collide an atom in ground state that the gap between energy levels of atom is greater than energy of photon?It seems that the medium absorbs light and transform to heat?

Usually most atomic transitions are in the visible range. So if you have a light with a slightly lower energy, then that means your light is in the infrared range.fxdung said:Why the medium become warmer when it is shined with light?What happen when it absorbs light?
A low energy photon is a particle of light with low energy, meaning it has a longer wavelength and lower frequency compared to higher energy photons. Low energy photons are typically in the visible or infrared range of the electromagnetic spectrum.
An atom in the ground state is the lowest energy state an atom can be in. This means that all of the atom's electrons are in their lowest possible energy levels or orbitals. In this state, the atom is considered to be in its most stable form.
When a low energy photon collides with an atom in the ground state, the atom's electrons can absorb the energy from the photon and move to a higher energy level. This process is known as excitation. Alternatively, the photon can be scattered or reflected off the atom without any energy transfer.
The energy of the photon determines whether it will be absorbed, scattered, or reflected by the atom. Low energy photons are more likely to be absorbed and cause excitation of the atom's electrons, while higher energy photons are more likely to be scattered or reflected.
Yes, a low energy photon can cause an atom to emit a photon through a process called spontaneous emission. This occurs when an excited electron in the atom returns to its ground state, releasing the excess energy as a photon. The emitted photon will have the same energy as the absorbed photon, resulting in a lower energy state for the atom.
