Question

The sharpness of the sound made by a string depend on its

Answer 1

Answer:

The string of a guitar is like a stretched string fixed at both ends, and the frequency of a stretched string is directly proportional to the tension in the string,

f∝

T

,

When the string is tightened, tension T in the string increases, hence frequency f also increases. As the pitch of a sound depends upon its frequency, therefore, its pitch also increases.
