Energy of electrons and change in energy state

E=h * n
energy of a photon where h=plank's constant (6.63x10^-34 J x S) and n = FREQUENCY
C=speed of light
3.00x10^8 m/s
C= v * (wavelength)
v=frequency(hertz); wavelength MUST BE IN METERS
(delta)E when electron changed levels
= -2.18x10^-18*Z^2*(1/ni^2 - 1/n2^2) where Z=atomic charge (ONLY FOR SINGLE ELECTRON SPECIES)
rhydberg constant (Rh)=
=2.18 x 10-18 J
