Photon Wavelength Ratio in Hydrogen
A hydrogen atom absorbs a photon and its electron moves from $$n=1$$ to $$n=3$$. If the electron then transitions to $$n=2$$, what is the ratio of the wavelength of the emitted photon (from $$n=3$$ to $$n=2$$) to the wavelength of the initially absorbed photon (from $$n=1$$ to $$n=3$$)?
