Quantum Theory and Quantum numbers
Electrons behave like waves. They give off wavelengths of light dependent on the energy level to which
they move.

Scientific notation must be used when doing these equations. Use on calculator or do long hand.
When dividing exponents, subtract
When multiplying exponents, add
λ= h/mv wavelength of energy emitted by electrons dependent on Planck’s /momentum of electron; its
mass x its velocity
λ= h/mv
