What is the wavelength (in nanometers) of a photon emitted during a transition from ni = 7 to nf = 3 state in the H atom?

Explanation:

To determine the wavelength; let's first calculate the energy (E) change of the transition by using the Rydberg constant

Now; to calculate the wavelength by using the formula:

To nanometers; we have:

is has three carbons, so the answer is propylamine.
