The electron in a hydrogen atom is excited from the quantum energy level n = 1 to n = 4. (a) How muchenergy is absorbed by the electron? (b) What are the frequency (v) and wavelength (2., in nanometers) ofthe photon absorbed by the electron? (c) What is the energy change (AE, in Joule) when this electronjumps from the quantum energy level n =4 to n= 2? (d) Calculate the wavelength (in nm) of the photonemitted by this electronic transition. (E, = -(2.18 x 10-18 J)/n²; h= 6.63 x 10-34 J.s; c = 3.00 x 10° m/s)
