What is Frequency (f)?

Frequency (f) is how often something happens over time, like counting beats in a song or waves in the ocean.

Imagine you're clapping your hands. Each time your hands come together, that's one beat. If you clap 10 times in 5 seconds, that means you’re clapping 2 times every second. That number, how many times something happens in one second, is called frequency, and we write it as f.

Think of a bouncing ball. Every time it goes up and down, that's one full cycle. If the ball bounces 10 times every 5 seconds, its frequency is 2 cycles per second.

Or imagine a metronome, that little tool musicians use to keep a steady beat. The faster it ticks, the higher the frequency, just like your clapping gets quicker and quicker!

Frequency helps us describe how fast things repeat. A radio wave with a high frequency has many waves passing by each second, while one with a low frequency has fewer. So whether you're listening to music or watching a bouncing ball, frequency is the number that tells you how often something happens, and it's just like counting your own claps!
