Answer:
Hertz
Step-by-step explanation:
The number of oscillations or vibrations per unit time is called frequency of a wave. The time taken to complete one oscillation is called time period of a wave. There is relation between the frequency and the time period. It is given by :
is the frequency of a wave
The SI unit of T is second (s). So, the SI unit of frequency is
or Hertz. So, the unit of frequency is Hertz.
