In a certain vacuum tube, electrons evaporate from a hot cathode at a slow, steady rate and accelerate from
rest through a potential difference of 45.0 V. Then they travel 28.0 cm as they pass through an array of slits
and fall on a screen to produce an interference pattern. If the beam current is below a certain value, only
one electron at a time will be in flight in the tube. In this situation, the interference pattern still appears,
showing that each individual electron can interfere with itself. What is the maximum value for the beam
current that will result in only one electron at a time in flight in the tube?
A 75 mW laser produces a (polarized) beam of 595 nm light.
This light reflects normally off an object that reflects 90 percent of the incident energy. How long does it take this laser to give the surface a momentum of 0.005 kgm/s
If the rms electric field inside the beam is 1600 v/m, what is the radius of the beam?

- A limitation on how many spectra per second can be recorded by a time-of-flight mass spectrometer is the time it takes the slowest ion to go from the source to the detector.

If you place another conducting surface in a position at which it can catch these electrons, and connect these two conductors by another conductor such as a wire, you can generate a so-called photoelectric current. Suppose the work function of a particular metal is 4.8 x 10-19 J.
