What happens during absorption and emission?

Absorption: an electron moves to a higher energy level. Emission: an electron moves to a lower energy level and releases a photon.

How does the energy gap affect a photon?

Larger gap = higher energy, higher frequency, shorter wavelength. Smaller gap = lower energy, lower frequency, longer wavelength.
