On this day, 5th April 1913, Niels Bohr completed his groundbreaking paper concerning quantum theory of the hydrogen atom, ‘On the constitution of atoms and molecules’:
ν = 2π²me⁴/h³•(1/τ₂² - 1/τ₁²)
Where;
ν - frequency of the radiation
Niels Bohr theory for the hydrogen atom was based on quantum theory, that energy is transferred only in certain well-defined quantities. Electrons should move around the nucleus but only in prescribed orbits. When jumping from one orbit to another with lower energy, a light quantum is emitted. Bohr’s theory could explain why atoms emitted light in fixed wavelengths.
