(a) Calculate: (i) the energy spacing AE between the ground state and the first excited
state of the hydrogen atom; (ii) and the ratio AE/E between the spacing and the ground state
energy.
(b) Consider now a macroscopic system: a simple pendulum which consists of a 5 g mass
attached to a 2 m long, massless and inextensible string. Calculate (i) the total energy E1 of
the pendulum when the string makes an angle of 60° with the vertical; (ii) the frequeney of the
pendulum's small oscillations and the energy AE of one quantum; and (iii) the ratio AE/E1.
(c) Examine the sizes of the ratio AE/E1 calculated in parts (a) and (b) and comment on
the importance of the quantum effects for the hydrogen atom and the pendulum.
a) How many distinct angles from the vertical axis can the orbital angular momentum vector L make for an electron with l = 7?
b)Calculate the smallest possible angle the L can make with respect to the vertical axis. (Hint: The smallest angle occurs when ml takes the maximum allowed value. Sketch L in that case and compare the vertical component, which is related to ml, to the magnitude of L, which is related to l.)
an angular momentum vector has a maximum z component of +3ℏ, how many different z components can it have?
