3.
A resonant cavity that will operate in the PRIMARY
mode on a
wavelength of 3 centimeters will have length, width,
and height
respectively of
a.
L = 3 cm, W = 3 cm, H = 6 cm.
b.
L = 6 cm, W = 6 cm, H = 3 cm.
c.
L = 1.5 cm, W = 1.5 cm, H = 1.3 cm.
d.
L = .75 cm, W = .75 cm, H = 3.5 cm.
4.
The electric and magnetic fields inside a resonant cavity are always
a.
parallel to each other.
b.
perpendicular to each other.
c.
parallel to the coupling probes.
d.
perpendicular to the coupling probes.
5.
The resonant cavity shown in Figure 99 uses slot coupling or electron
coupling to insert energy into the cavity.
The electric field
developed in the cavity will be at its maximum strength
a.
at the center of the cavity, and the magnetic field will be at
its maximum strength on the edges of the cavity.
b.
at the center of the cavity, and the magnetic field will be at
its minimum strength on the edges of the cavity.
c.
on the edges of the cavity, and the magnetic field will be at its
maximum strength in the center of the cavity.
d.
on the edges of the cavity, and the magnetic field will be at its
minimum strength in the center of the cavity.
