These electronic Electrical power degrees happen at extremely certain intervals. That is why a certain atom might absorb only certain photons. The energy of the photon needs to match, more or less accurately, the quantity of Strength an electron would need in an effort to jump from a single degree to a different.

If we look at an easy Bohr design from the atom, through the early twentieth century, we think in the electrons orbiting the nucleus in shells. Every single shell is slightly farther from the nucleus, and at a greater energy compared to a person underneath it. If an atom absorbs a photon, among the list of electrons receives promoted to an increased level.

And what occurs into the electrons every time they interact with The sunshine? Nicely, photons have Vitality, so in the event the photons connect with the electrons, they transfer their Strength into the electrons. We are saying the electrons turn into excited, or that they are promoted to an increased amount.
