Frequency is defined as which of the following?

• A. Number of times a wavelength repeats or completes a cycle
• B. The rate of current flow
• C. Electrical potential difference
• D. The power delivered to the load

Answer: (A)

Frequency is the number of times a wavelength repeats or a cycle completes in one second. It tells you how fast the wave is oscillating, with the standard unit being hertz (cycles per second). For example, a signal that completes one billion cycles each second has a frequency of 1 GHz. Frequency and period are inversely related: f = 1/T, so faster oscillations mean shorter periods. In avionics, frequency defines the carrier and helps determine propagation, modulation, and channel characteristics. The other terms describe different electrical quantities: current (rate of flow of electric charge), voltage (electrical potential difference), and power (energy delivered per unit time).
