Explain how electrons use light energy to move among energy levels within an atom.

explained

Explanation:

Electrons use light energy to move among energy levels within an atom because of the following reason

Electrons in each orbit around an atom have some  specific energy. However, they can emit or absorb photons of the energy  equal to difference of the energy between these specific energy levels within an atom. If the electron absorbs an photon, it can move up the energy level, if the electron emits a photon, it can move down to a energy level.

myth. it was once thought that animals, including cats and dogs, could only see in black and white. however, scientists have proven this to be a myth. in all animals, including humans, the perception of colour is determined by the presence of cells in the eye called cone photoreceptors.
