# Can a photon with energy greater than energy level difference of atom.

• fxdung
In summary, the conversation discusses the absorption of a photon with energy greater than the energy level difference of an atom. The concept of Compton scattering and its application to bound electrons is also mentioned. The complication of the binding energy not being small compared to the photon energy is addressed, and the suggestion is made to include the word "bound" in a search for more information.

Can a photon with energy greater than energy level difference of atom be absorbed by atom?Is there any case in that photon share a part of energy for atom and keep other part of energy for itself?

Are you familiar with Compton scattering? Google for “Compton bound electron”

But when the wave leng of photon not short as X-ray then what does it happen?

Then you cannot make the simplifying assumption that the binding energy is small compared with the photon energy, and the math gets more complicated. That’s why I suggested that you include the word “bound” in the search - that will find some papers that cover this complication.

## 1. Can a photon with energy greater than the energy level difference of an atom be absorbed?

Yes, a photon with energy greater than the energy level difference of an atom can be absorbed. This is known as the photoelectric effect, where the excess energy of the photon is converted into kinetic energy of the electron.

## 2. What happens if a photon with energy greater than the energy level difference of an atom is absorbed?

If a photon with energy greater than the energy level difference of an atom is absorbed, the excess energy is used to excite the electron to a higher energy level. The electron may then emit this excess energy as a lower energy photon or transfer it to other particles through collisions.

## 3. Is it possible for a photon with energy greater than the energy level difference of an atom to pass through the atom without being absorbed?

Yes, it is possible for a photon with energy greater than the energy level difference of an atom to pass through the atom without being absorbed. This is known as transmission, where the photon does not interact with the atom and continues on its path.

## 4. Can a photon with energy greater than the energy level difference of an atom cause ionization?

Yes, a photon with energy greater than the energy level difference of an atom can cause ionization. This occurs when the excess energy of the photon is used to completely remove an electron from the atom, resulting in an ion.

## 5. How does the energy of a photon affect its interaction with an atom?

The energy of a photon determines the type of interaction it will have with an atom. If the energy is less than the energy level difference of the atom, the photon will not be absorbed. If the energy is greater than the energy level difference, the photon may be absorbed, transmitted, or cause ionization depending on the amount of excess energy.
