1. a) Right-hand rule.

See this RF Cafe Labs experiment that proves the claim.

2. b) Lissajous waveform (lē'-su-zhOO").

Named after Jules Antoine Lissajous.

3. b) frā-nĕl'  -  that's right, it is NOT pronounced frĕz-nĕl'

4. a) Lowpass

Low frequencies easily pass through the series inductors and do not pass through the shunt capacitors.

5. b) 4

Each reactive component (2 inductors + 2 capacitors) creates a pole in the transfer function.

6. c) Microstrip

Microstrip uses a conductor running over top of a ground plane, with a dielectric in-between.

7. b) 90° H-Plane bend

The mnemonic used for waveguide is that an E-Plane bend curves along the narrow side (the "E"asy bend), and that a H-Plane bend curves along the wide side (the "H"ard bend). There is no such thing as a Maxwell bend.

8. c)  62 kΩ, ±10% = 3 (62 x 10³ = 62 kΩ), Silver = ±10%

9. a) Tin whiskers
