Electromagnetic Radiation
The distance from crest to crest of a wave is called _______.
wavelength
What is an atomic emission spectrum?
The set of frequencies of electromagnetic waves given off by a certain atom
What does Hund's rule state?
That electrons occupy orbitals of the same energy (i.e. within the same sublevel) in such a way that as many electrons as possible have the same spin.

What is the photoelectric effect?
The photoelectric effect occurs when electrons are emitted from a metal's surface when light of a certain frequency shines on it.
What equation can you use to determine either wavelength or frequency, given the other value?
the speed of light = frequency x wavelength
