According to the quantum-mechanical model, the higher the "n" level, the higher the energy. As a result, the transition from 3p --> 1s would be ea greater energy difference than a transition from 2p --> 1s. The lower energy transition would have the longer wavelength. As a result, the 2p --> 1s transition would produce a longer wavelength.
