Concept and Principle:
- When an electron moves from a higher state to a lower state it will release energy in the form of electromagnetic radiation. The wavelength of the released photon is given by the Rydberg formula.
- Rydberg formula is given by,
Here R∞ is the Rydberg constant and has a value of 1.097373 × 107 m-1, and n1 and n2 are the states in which transition takes place.
- Combining this equation with the energy of the photon we get,
Here n1 and n2 are the states in which transition takes place.

Ignore the effect of electron spin.arrow_forwardPlease 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…arrow_forward
