Frequency is really important in how sound waves work. Let’s break it down into simpler ideas:

• Pitch: Higher frequencies make higher pitches. For example, a whistle has a high pitch, while a deep drum has a low pitch. This difference is all about frequency.

• Wavelength: As the frequency gets higher, the wavelength gets shorter. You can think of sound traveling like a wave. The formula $v = f \lambda$ helps explain this. Here, $v$ is how fast sound travels, $f$ is frequency, and $\lambda$ is the wavelength.

• Intensity: Higher frequencies lose energy fast. This means they don’t travel as far as lower frequencies. So, you might hear a high sound close up, but it fades quickly as you move away.

• Timbre: Different frequencies help create the unique sound of each instrument. That’s why a piano and a guitar sound different, even when they play the same note.

These points show just how much frequency influences our experience of sound!
