How close must the wavelength of a photon be for an atom to absorb it?

This means that a photon's energy must match the energy difference between the electron's orbitals in order for the electron to absorb it. If the photon's energy is equal to or greater than the energy difference, the electron will be excited to a higher energy level and then quickly return to its original state, emitting the photon once again. In summary, for an atom to absorb a photon, the photon's wavelength must be very close to the energy needed for an electron jump in the atom.

When a photon has a wavelength close to the energy needed for an electron jump in an atom, the atom will absorb the photon. How close must the wavelength be to the energy required for the atom to still absorb it?

Other members correct me if am wrong but I believe most photon energies are absorbed the electron. Most times the photon has not enough energy to excite the electron to an upper energy level, so the electron does not move and absolves the light.
If the photon has equal or more energy than the energy difference of the electron cloud orbitals the electron is excited up where it imminently comes back down and remit the photon.

Exact, photons arise from complementary quantization phenomena
 

1. How is the wavelength of a photon related to an atom's ability to absorb it?

The wavelength of a photon is directly related to an atom's ability to absorb it. This is because atoms have specific energy levels, and a photon with a wavelength that matches the energy difference between two levels can be absorbed by the atom.

2. What is the minimum wavelength of a photon that an atom can absorb?

The minimum wavelength of a photon that an atom can absorb depends on the energy levels of the atom. Each atom has a unique set of energy levels, so the minimum wavelength will vary from atom to atom.

3. Can an atom absorb a photon with a longer wavelength than its energy levels?

No, an atom cannot absorb a photon with a longer wavelength than its energy levels. This is because the energy of a photon is directly proportional to its wavelength. If the energy of the photon is greater than the energy difference between the atom's levels, the excess energy will not be absorbed.

4. What happens if the wavelength of a photon is too far from an atom's energy levels?

If the wavelength of a photon is too far from an atom's energy levels, the photon will not be absorbed by the atom. It may be scattered or transmitted through the material, but it will not interact with the atom in a way that causes absorption.

5. Is there a maximum wavelength of a photon that an atom can absorb?

There is no specific maximum wavelength of a photon that an atom can absorb. However, as the wavelength of a photon increases, its energy decreases. Eventually, the energy of the photon will be too low to cause an electron transition in the atom, and it will not be absorbed.
