Question
Which of the following units can be used to measure the frequency of a sound wave?
Answer: Option A
:
A and C
The number of waves produced per unit time is called frequency (f). The time taken to produce one complete wave is called timeperiod (T). The frequency of a wave is equal to inverse of timeperiod i.e, f = 1T.
The SI unit of frequency is hertz (Hz).
1 Hz = 1 s−1
