energy of a photon

E = hv

l

angular momentum quantum number

n

principal quantum number

m_s

spin projection quantum number

Bohr Model

the atom as a small, positively charged nucleus surrounded by electrons that travel in circular orbits around the nucleus—similar in structure to the Solar System

photoelectric effect

the production of electrons or other free carriers when light is shone onto a material

n limit

1<=x

m_l limit

-l <= x <= l

m_s limit

-s <= x <= s

l limit

0 <= x <= n-1

frequency

in a wave, number of crests of a wave that move past a given point in a given unit of time

wavelength

in a wave, the distance between two successive wave crests or troughs

amplitude

in a wave, the distance from the center line (or the still position) to the top of a crest or to the bottom of a trough.

wavelength equation

lambda = h/(mv)

m_l

magnetic quantum number

quantum numbers

n, l, m_l, m_s
