Frequency

Real World Example

Imagine you're standing in line at a busy coffee shop, trying to figure out how quickly the barista can serve each customer. Just as you'd count how many people are served in a minute to gauge the speed of service, frequency measures how many complete cycles or vibrations occur in a second, using hertz (Hz) as the unit. In both scenarios, you're essentially counting occurrences over a set period: in the coffee shop, it's customers served per minute, and with frequency, it's cycles per second.
