Find wavelength of photon emitted if electron transition

Consider an electron in an in?nite well of width 1.8 nm. What is the wavelength of a photon emitted when the electron in the in?nite well makes a transition from the ?rst excited state to the ground state?

The value of ¯h is 1.05457 × 10^-34 J · s, the Bohr radius is 5.29177 × 10^-11 m , the Rydberg constant for hydrogen is 1.09735 × 10^7 m^-1, the ground state energy for hydrogen is 13.6057 eV , and the speed of light is 2.99792 × 10^8 m/s. 1 eV = 1.60218 × 10^-19 eV .
