 Title: Quantum Mechanics problem 2.11 Post by: FogRit on July 17, 2006, 02:04:47 AM Title : Introduction to Quantum MechanicsAuthor : David J. GriffithsEditoin : 2nd EditonPublisher : Pearson Prentice Hall*Problem 2.11 หน้า 50(a) Compute and , for the states (Equation 2.59) and (Equation 2.62), by explicit integration. Comment: In this and other problems involving the harmonic oscillator it simplifies matters if you introduce the variable and the constant .Equatoin 2.59  Equaton 2.62               ---        ----      ----          ----- Title: Re: Quantum Mechanics problem 2.11 Post by: FogRit on July 17, 2006, 02:15:58 AM (b) Check the uncertainty principle for these states.state 0เพราะฉะนั้น state 0 ไม่ขัด uncertainty principlestate 1เพราะฉะนั้น state 1 ไม่ขัด uncertainty principle Title: Re: Quantum Mechanics problem 2.11 Post by: FogRit on July 17, 2006, 02:28:27 AM (c) Compute (the average kinetic energy) and (the average potential energy) for these states. (No new integration allowed!) Is their sum what you would expect?พิจารณาที่ state 0เพราะว่าพลังงานรวมในระบบคือ พลังงานจลน์ + พลังงานศักย์ ตามที่หวังไว้
