1 Can you show that the orbital angular momentum of an electron in any given direction (e.g., along the z-axis) is always less than or equal to its total orbital angular momentum? In which cases would the two be equal to each other?
(b) Is the result in part (1) true for a classical object, such as a spinning top or planet?
Assume we are in an alternate universe with different physical laws. Electrons in this universe are described by four quantum numbers with meanings similar to those we use. We shall call the alternate universe’s quantum numbers p, q, r, and s. The rules for these quantum numbers are as follows:
• p = 1, 2, 3, 4, 5, ...
• q may take positive odd integers and q ≤ p
• r takes on all even integer values from −q to +q (zero is considered an even number)
• s = +1⁄2 or −1⁄2
(a) How many electrons can have p = 4, q = 3?
(b) How many electrons can have p = 3, q = 0, r = 0?
(c) How many electrons can have p = 6?
(d) What is the maximum occupancy of electrons in p = 3?

(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.
