55 Questions for Chapter 1: The Dawn of a New Age

  1. It is shown in section 6.1 that for the E<U0 potential step, B=-α+ikα-ikA. Use it to calculate the probability density to the left of the step:

  2. You are in a bus travelling on a straight road at 20m/s. As you pass a gas station, your clock and a clock in station read precisely 0. You pass another gas station 900m farther down the road. (in the frame of reference of the gas stations., all gas station clocks synchronized.) (a) As you pass the: second station, do you find its clock to be ahead of, or: behind your own clock and (b) by how much?

  3. A supersonic: - plane travels al 420 m/s. As this plane passes two markers a distance of 4.2km apart on the ground, how will the time interval registered on a very precise clock onboard me plane differ from 10s?
