Which property of waves is measured in Hertz?

1. Amplitude

2. Frequency

3. Velocity

4. Wavelength

The correct answer is: Frequency

The property of waves measured in Hertz is frequency. Hertz (Hz) is the unit of measurement that quantifies the number of cycles of a wave that occur in one second. When considering wave behavior, frequency indicates how often a specific point on the wave, such as a crest or trough, passes a given point in a second. In practical terms, a high-frequency wave has more cycles per second compared to a low-frequency wave, leading to different characteristics such as pitch in sound waves or color in light waves. This frequency measurement is fundamental in numerous fields, including physics, audio technology, and telecommunications, as it directly impacts how waves behave and interact with various mediums. Understanding this concept is crucial in studying wave properties and their applications in real-world scenarios, such as radio frequencies, musical notes, and other oscillatory phenomena.
