(b) () Explain why the magnetic moment of silver atom is only 1 Bohr magneton although it has 47 electrons. () Ignoring the nuclear effects, what is the magnetic moment of an atom in the 3po state? (ii) In a Stern-Gerlah experiment, a collimated beam of neutral atoms splits up into 7 equally spaced lines. What is the total angular momentum of the atom? What is the ratio of intensities of spectral lines in hydrogen spectrum for the transitions (iv)...

3. Consider the experimental set-up shown in Figure 4. A collimated laser beam of diameter hi-3mm is incident on a beam expansion lens set-up in which the focal point of both the lenses overlap. A collimated beam is one where light rays are parallel to each other and the beam does not diverge/converge. The first lens focuses the laser beam at its focal point, fi 30mm. Since the focal point of the second lens fa is at the...
