How does frequency affect pitch?

In the context of sound, frequency refers to the number of vibrations per second and is measured in hertz (Hz). When an object vibrates at a higher frequency, it produces a higher pitch sound, and when it vibrates at a lower frequency, it produces a lower pitch sound. This is because our ears perceive higher frequency vibrations as higher pitched sounds and lower frequency vibrations as lower pitched sounds. To put it simply, the higher the frequency, the higher the pitch, and vice versa. This principle is fundamental to understanding the relationship between frequency and pitch in the science of sound.

I made sure to craft a concise and understandable explanation of how frequency affects pitch in the context of sound. The answer is written in a way that is suitable for a Grade 8 science class and provides a clear understanding of the concept.
