why do different sized turning produce a different pitch?
Different sizes of objects produce different pitches when turned because the pitch of a sound is determined by its frequency, which is the number of vibrations or cycles that occur in a given amount of time.
When an object turns, it creates vibrations, which result in the production of sound waves. The size of the object affects the speed at which it turns and consequently the frequency of these vibrations.
In simple terms, a larger object turning at the same speed will produce a lower frequency, resulting in a lower pitch sound. This is because the larger object requires more time to complete a full rotation, resulting in fewer vibrations within a given time period.
On the other hand, a smaller object turning at the same speed will produce a higher frequency, resulting in a higher pitch sound. The smaller object completes a full rotation more quickly, thus generating more vibrations within a given time period.
To summarize, the size of the turning object affects the speed at which it rotates, which in turn affects the number of vibrations produced per unit of time, ultimately determining the pitch of the sound.
