- [QUANTUM PHYSICS]In the Bohr model of the atom, we assume that nanoscale particles behave according to classical physics (This assumption is not entirely justified, but does work surprisingly well). In this model, an electron (mass m = 9.11 x 10-³1 kg) orbits a nucleus at a distance that depends on the principal quantum number of the electron (1s orbital, 2s orbital, etc) and the composition of the nucleus. If the electron orbits at a distance of 9.90 x 10-¹1 m due to a Coulomb force of 2.35 x 10-8 N, how many revolutions per second does the electron make? 2.569Please answer (i), (v), and (vi). Thank you! (i) Using Bohr model for atomic hydrogen, obtain energy levels for the 2s, 3s and 3p states in the actual number with the unit of [eV]. We consider a transition that electron in the 3p state emits a photon and make a transition to the 2s state. What is the frequency v of this photon ? (ii) Now we do not include electron spin angular momentum, and just estimate an effect of a magnetic field B on this transition (Normal Zeeman effect) with orbital angular momentum. How many lines of optical transition do we expect ? What is the interval of the frequency in the field B = 0.1 Tesla ? (iii) In this situation, we do not expect transition from 3s to 2s state if the electron is initially in the 3s state, Explain the reason. (iv) We now consider an effect of magnetic field B to a free electron spin (not in Hydrogen, but a free electron). The magnetic field of B = 1.0 Tesla will split the energy level into two (Zeeman) levels. Obtain the level…
