2) A particle confined in an infinite well of length a =100 X 1014 has an energy level Er1 = 32.9 McV and an adjacent energy level En+1 = 51.4 MEN (1. Determine the value of n. Answer: n = 4 1). Determine the mass of the particle. What elementary particles have this mass? Answer: 1.67 x 10'27 kg ; proton, neutron 3) An electron trapped in an innite well has a ground state energy of 9.0 eV. :1. If a photon were emitted when the electron jumps from then = 2 state to the n = 1 state, what would its wavelength be? Answer: 46 nm
