, 1. What is the primary function of a waveguide in
electromagnetic applications?
- a) Amplification of signals
- b) Propagation of electromagnetic waves
- c) Storage of electrical energy
- d) Conversion of energy to heat
Answer: b) Propagation of electromagnetic waves
Rationale: Waveguides are structures that guide
electromagnetic waves from one point to another, confining
the wave energy.

2. Which of the following materials has the highest
electrical conductivity?
- a) Copper
- b) Aluminum
- c) Silicon
- d) Gold
Answer: d) Gold
Rationale: Gold has a higher conductivity compared to
copper and aluminum, though copper is often used due to
cost and availability.

3. In a medium with a permittivity of ε and permeability of
μ, the speed of electromagnetic waves is given by which of
the following equations?
- a) c = εμ
- b) c = 1/(εμ)^(1/2)
- c) c = εμ
- d) c = ε/μ
Answer: b) c = 1/(εμ)^(1/2)
Rationale: The speed of light in a medium is inversely
