Figure 6-4.—Spacing between plates.
Q-6. What effect does closer spacing of plates have on the electron beam?
DIFFERENCE OF POTENTIAL.— The potential on the plates (figure 6-5) can be varied to cause
a wider or narrower deflection angle. The greater the potential, the wider the deflection angle.
Figure 6-5.—Differences of potential.
Q-7. Is the deflection angle greater with higher or lower potential on the plates?
BEAM ACCELERATION.—The faster the electrons are moving, the smaller their deflection angle
will be, as shown in figure 6-6.

Q-8. Is the deflection angle greater when the beam is moving faster or slower?
