How do photons cause matter to move?

Click For Summary
SUMMARY

Photons cause matter to move through the interaction of electromagnetic (EM) waves with charged particles, such as electrons in atoms. When a photon collides with an atom, the electron absorbs the energy and transitions to a higher energy state. If the energy is not utilized, the electron returns to a lower energy state, emitting radiation in the process. This mechanism explains how sunlight increases temperature and accelerates the motion of gas particles in the atmosphere, as the electric field of the EM wave exerts a force on the charged particles.

How does light cause matter to move? For example, when a photon collides with an atom, an electron absorbs the photon and moves to a higher energy state. If the energy is not used then the electron falls back to a lower energy state and emits radiation. I am unsure of how the photon in the above example causes the motion of an atom. A more specific question is how does sunlight increase temperature, or speed up the motion of the gas particles in the atmosphere.

Light is an EM wave whose fields have what's called vectors. This means that an electric charge that the wave passes over will feel a force from the electric field of the EM wave in a particular direction. It is this force that causes an interaction. Each individual interaction takes a specific amount of energy based on the frequency of the wave. We call these "photons".
