Question

state the effect on the pitch of the sound

Answer 1

The four properties of the string that affect its frequency are length, diameter, tension, and density. These properties are described below: When the length of a string is changed, it will vibrate with a different frequency. Shorter strings have higher frequency and therefore higher pitch.

Answer 2

Sound B has a lower pitch (lower frequency) than Sound A and is softer (smaller amplitude) than Sound C. The frequency of a sound wave is what your ear understands as pitch. A higher frequency sound has a higher pitch, and a lower frequency sound has a lower pitch.
