The period of the string vibrating at frequency of 20 Hz will be
[tex]T=\dfrac{1}{20} sec[/tex]
The time period is the time taken to complete one cycle in formula it is given by
[tex]T=\dfrac{1}{f} sec[/tex]
Here f= frequency
now to calculate time period we have f=20 Hz
[tex]T=\dfrac{1}{20} sec[/tex]
Hence The period of the string vibrating at frequency of 20 Hz will be
[tex]T=\dfrac{1}{20} sec[/tex]
