Answer 1

● If the tension in the string of a guitar is increased keeping other factors unchanged, then the sound produced as higher pitch.

● So in the given options option A is correct answer for the given question.

● If the tension in the string increases this results in the increase in the frequency of the wavelength and travelling time of the wave decreases.

● This results in the increase in the pitch of the sound wave.
