The diagram shows three energy levels of a particular atom as well as its ionization energy. A 3100-wavelength photon releases an electron from level 2 of the atom, (and transfers all of its energy to the electron).
A. What is the kinetic energy of the electron being released?
B. What is the wavelength of the released electron? (Wavelength de Broy)
