Does it not slow down? As it travels at C and then to a relative 0.
When a photon is absorbed by an atom, the energy of the photon is transferred to an electron in the atom. This causes the electron to move to a higher energy level or even be ejected from the atom entirely, depending on the energy of the photon.
In order for an atom to absorb a photon, the energy of the photon must match the difference in energy between the electron's current energy level and the higher energy level it is moving to. This process is known as absorption spectroscopy and is used to study the energy levels of atoms.
The color of light that is absorbed by an object is determined by the energy levels of the atoms in the object. Each color of light corresponds to a specific energy level, so if the energy of the photon matches the energy level of an atom, that color of light will be absorbed.
Yes, photons can be absorbed by other particles such as molecules and even larger objects like planets. However, the process of absorption is still the same - the energy of the photon is transferred to the particle, causing a change in its energy state.
After a photon is absorbed, it no longer exists in its original form. The energy of the photon has been transferred to the absorbing particle, causing a change in its energy state. The absorbed photon may then be re-emitted as a new photon with a different energy, or it may be converted into a different form of energy, such as heat.
