(c) [x,p 2 ] = ? I have added two problems: Chapter 5 Problem 27 A woman is walking along Intercampus drive. She has a mass of 52 kg and is walking at 1 m/s. (a) She is not paying careful attention and is walking straight towards the wall of the new BME/Optics building. Assume that the wall is infinitely hard and that she can be described as a plane wave (a free particle). As she “bounces” off the wall, her incident and reflected wavefunctions interfere. What is the spacing of the nodes in her | Ψ | 2 ? (b) Next, she approaches a curb of height 25 cm and steps over it. as we will see in class this week, quantum mechanically she as a finite probability of bouncing off (being reflected off) the curb. What is her reflection coefficient? HW2 Due Friday, 2/16/2007 5:15 pm Continue reading Chapter 6 E&R E&R Chapter 6 Questions 7, 9, 11
