n22
n12
R is the Rydberg constant = x107 m-1
for the visible series, n1 = 2 and n2 = 3, 4, 5, ...

The Bohr explanation of three series of spectral lines emitted by the H atom.

10. Tools of the Laboratory
Figure B7.1
Flame tests and fireworks.
strontium 38Sr
copper 29Cu
The flame color is due to the emission of light of a particular wavelength by each element.
Fireworks display emissions similar to those seen in flame tests.
copper 29Cu
