a string vibrates at a frequency of 20hz what is its period

Sagot :

Period = 1 / frequency

20 Hz means 20 per second

1 / (20 per second) = 0.05 second

The period of an oscillation is the time to complete one cycle. Since the frequency is the number of cycles per second, it turns out that the period is the reciprocal of the frequency, f:

[tex] T=\frac{1}{f} [/tex]

in this problem, the frequency of vibration of the string is f=20 Hz, therefore the period is

[tex] T=\frac{1}{f}=\frac{1}{20 Hz} =0.05 s [/tex]
