Question

b) The frequency of a tuning fork is 100 Hz. What is its time period of vibration?​

Answer 1

Answer:

Usually, the frequency is measured in the Hertz unit, named in honor of the 19th-century German physicist Heinrich Rudolf Hertz. The hertz measurement, abbreviated Hz, is the number of waves that pass by per second.

So, if your frequency is 100 Hz it means that time taken for one full wave or complete oscillation will be 1/100 sec.

the time period will be T = 0.01 s

Or, T = 1 / Frequency
