What is the unit for measuring frequency?

The unit for measuring frequency is Hertz (Hz). Frequency is defined as the number of oscillations or cycles that occur in a unit of time. Specifically, one Hertz is equivalent to one cycle per second. This means that if a wave has a frequency of 5 Hz, it completes 5 cycles in 1 second.

In the context of waves, understanding frequency is crucial because it determines the pitch of sounds and the color of light, among other characteristics. By measuring how many times a wave repeats in one second, we can categorize and analyze different types of waves in physics. Other units mentioned, such as Joules, meters, and seconds, refer to energy, distance, and time respectively, which are relevant in their contexts but do not measure frequency directly.
