Dear Student,1
 Number of oscilations, n=15     time taken, t=0
1 sec    Frequency, ν =Number of oscilations time taken=150
1=150 HzAnd we know that, Humans can detect sounds in a frequency range from about 20 Hz to 20 kHz
 And 150Hz lies between 20 Hz and 20 KHz Hence the sound is audible sound

  Two factors on which frequency of any string instrument depend:-    1
) Length of the string     2
) Tension produced in stringFor remaining queries we request you to post them in separate threads to have rapid assistance from our experts
