The number of waves that pass each second is called?

• A. Period
• B. Frequency
• C. Wavelength
• D. Amplitude

Answer: (B)

Frequency is the number of waves that pass a point in a given amount of time. When we talk about waves per second, we’re measuring frequency in hertz (Hz). The faster the waves pass, the higher the frequency. It’s the reciprocal of the period, which is the time it takes for one complete wave to pass (f = 1/T). The other terms describe different properties: period is the time for one wave to pass, wavelength is the distance between successive crests, and amplitude is the height of the wave. So the measure described as waves per second is frequency.
