* Frequency and Pitch: The pitch of a sound is determined by its frequency, the number of vibrations per second. Higher frequencies correspond to higher pitches.
* Size and Thickness:
* Smaller Size: A smaller gong has a shorter vibrating surface. This means it takes less time for the sound wave to travel across the gong, resulting in a higher frequency and a higher pitch.
* Thinner Material: A thinner gong has less mass. This means it vibrates more easily and at a higher frequency, again producing a higher pitch.
Think of it this way: Imagine a guitar string. A shorter, thinner string vibrates faster, producing a higher note than a longer, thicker string. The same principle applies to gongs.
