An atom absorbs the light for a short time and then releases it.

The amount of energy that individual atoms absorb depends on their atomic number.

As a result, some atoms absorb light and enter the excited state.

The atoms absorb ultraviolet or visible light and make transitions to higher electronic energy levels.

What we have overlooked is that, when atoms absorb and emit light, they do so from what are called modes.

Thus, the atoms would absorb more photons if they moved towards the light source, due to the Doppler effect.

An atom or a molecule can absorb light and undergo a transition from one quantum state to another.

As a result, the receiving atom cannot absorb it.

The atoms should absorb some of the quasar light in a characteristic pattern.

A molecule or an atom absorbs at a certain wavelength.
