Use the same method as in the preceding problem toshow that a transition from a / 2,m/ 0 state to a/ 0 state is forbidden.

Simple Harmonic Motion Simple Harmonic Motion ● Period: time required for one cycle of periodic motion ● Frequency: number of oscillations per unit time ○ f= T ● A spring exerts a restoring force that is proportional to the displacement from equilibrium: ○ F=-kx ● A mass on a spring has a displacement as a function of time that is a sine or cosine ● If we call the period of the motion T - this is the time to complete one full cycle - we can write the position as a function of time. 2π ○ x=Acos( Tt) ○ ω =2π T ○ ω=2πf ● The position as a function of time: ○ ● The velocity as a function of time ○ ● The acceleration
