The quantity defined as the number of cycles that occur in one second is called

• A. Cycles per second
• B. Frequency of a wave
• C. Amplitude
• D. Wavelength

Answer: (B)

Frequency is the number of cycles that occur each second. It tells you how often the wave repeats per unit time and is measured in hertz (Hz). If a wave completes 60 cycles in one second, its frequency is 60 Hz, and the time for one cycle (the period) would be 1/60 second. Amplitude describes how tall the wave is (its strength or loudness in sound), and wavelength is the spatial distance between repeating points on the wave. The phrase “cycles per second” describes frequency, but the standard term for that quantity is frequency of a wave.
