What is the difference between an emission spectrum and an absorption spectrum? Please write a few sentences.

Spectra have been used to study the arrangements of electrons in atoms.An emission spectrum consists of a series of bright lines that converge at high frequencies.Such emission spectra provide evidence that electrons are moving from.A. lower to higher energy levels with the higher energy levels being closer together.B. lower to higher energy levels with the lower energy levels being closer together.C. higher to lower energy levels with the lower energy levels being closer together.D. higher to lower energy levels with the higher energy levels being closer together.
