In the **Bohr Equation**, the energy and wavelength a photon is related to its energy shell transitions.

## Bohr Equation

## Bohr Equation Example 1

What is the wavelength of a photon (in nm) absorbed during a transition from the n = 2 to n = 5 state in the hydrogen atom?

Determine the end (final) value of n in a hydrogen atom transition, if the electron starts in n = 5 and the atom releases a photon of light with an energy of 4.5738 × 10^{-19} J.

An electron releases energy as it moves from the 6^{th} shell to the 3^{rd} shell. If it releases 4.25 x 10^{9} kJ of energy at a wavelength of 915.7 nm, how many photons were released in the process?
