Rotational motion
(a) Show that [? ̂?,? ̂?] = ?ℏ? ̂?, [? ̂?,? ̂?] = ?ℏ? ̂?, [? ̂?,? ̂?] = ?ℏ? ̂?.
(b) Show that [? ̂2,? ̂?] = 0, and then, without further calculations, justify the remark that [? ̂2,? ̂?] = 0 for all ? = ?, ?, and ?. What does this mean in terms of uncertainty principles?

An important special case of the motion of a symmetric top occurs when it spins about a vertical axis. Analyze this motion as follows: (a) By inspecting the effective PE, U_eff(theta)=((L_z-(L_3)cos(theta))^2)/((2lambda_1(sin^2(theta)))+((L_3)^3)/(2lambda_3))+MgRcos(theta), show that if at any time theta=0, then L_3 and L_z must be equal. (b) Set L_z=(L_3=lambda_3)(w_3) and then make a Taylor expansion of U_eff(theta) about theta=0 to terms of order (theta)^2. (c) Show that if w_3>w_min=2sqrt(MgRlambda_1/((lambda_3)^2), then the position theta=0 is stable, but if w_3=w_min it is unstable....

3. (10 pts) Heisenberg Uncertainty Principle The uncertainty principle places a limit on specifying the location and momentum of a particle simultaneously. Δ?Δ? ≥ ℏ/2 This is a consequence of the wave nature of particles, which we can see by examining the uncertainty in the single-slit diffraction of light. (a) In single-slit diffraction, the width of the slit ? represents the uncertainty in x position of the beam, ∆?: ∆? = ? We can imagine that we can try to...
