Chapter 6: Q16E (page 224)
A particle moving in a region of zero force encounters a precipice---a sudden drop in the potential energy to an arbitrarily large negative value. What is the probability that it will 鈥済o over the edge鈥�?
I will definitely reflect for tending to infinite.

In the wide-barrier transmission probability of equation , the coefficient multiplying the exponential is often omitted. When is this justified, and why?
A ball is thrown straight up at . Someone asks 鈥淚gnoring air resistance. What is the probability of the ball tunneling to a height of?鈥� Explain why this is not an example of tunneling as discussed in this chapter, even if the ball were replaced with a small fundamental particle. (The fact that the potential energy varies with position is not the whole answer-passing through nonrectangular barriers is still tunnelirl8.)
What fraction of a beam of electrons would get through a wide electrostatic barrier?
Show that if you attempt to detect a particle while tunneling, your experiment must render its kinetic energy so uncertain that it might well be "over the top."
Example 6.3 gives the refractive index for high-frequency electromagnetic radiation passing through Earth鈥檚 ionosphere. The constant , related to the so-called plasma frequency, varies with atmospheric conditions, but a typical value is . Given a GPS pulse of frequency traveling through of ionosphere, by how much, in meters, would the wave group and a particular wave crest be ahead of or behind (as the case may be) a pulse of light passing through the same distance of vacuum?
