nano is
10^-9
emission of electrons from a metal when light shines on the metal
photoelectric effect
photoelectric effect happens because there is
a small number of electrons. when energy is applied, the electrons are released.

quantum
equation for energy
e=hv
what does e stand for
energy (joules)
h stands for
plancks constant
particle of electromagnetic radiation having zero mass and carrying quantum of energy
photon
lowest energy state of an atom
ground state
state in which an atom has a higher potential energy than it has in ground state
excited state
equation to solve for wavelength
c/v=lambda
equation to solve for frequency
c/lambda=frequency
