" Given: "mu_(s)=(3)/(2),mu_(oo)=(4)/(3)l

The magnetic moment vectors mu_(s) and mu_(l) associated with the intrinsie spin angular momentum S and orbital angular momentum l, respectively, of an electron are predicted by quantum theory (and verified expenmentally to a high accuracy) to be given by: mu_(s)=-(e//m) S, mu_(1)=-(e//2m)l Which of these relations is in accordance with the result expected classically? Outline the derivation of the classical result.

In the figure shown mu_(1),mu_(2),mu_(3),mu_(4) and mu_(5) are the refractive indices of the mediums 1,2,3,4 and 5 respectively. Consider the following: (1) mu_(1)=mu_(2) (2) mu_(3)=mu_(4)=mu_(5) (3) mu_(2) lt mu_(3) (4) mu_(4)gt mu_(5) Which of the above are correct?
