Question

To determine a waves' frequency, you must know the

Answer 1

B. number of oscillations in a given period of time.

Answer 2

Answer : Frequency equals number of oscillations in a given period of time.

Explanation :

The number of oscillations in a given period of time is known as the frequency of the wave. It is denoted by $\nu$. Its SI unit is hertz (Hz).

It is also defined as the inverse of time period i.e.

$\nu=\dfrac{1}{T}$

T is the time period.

Hence, the correct option is (B) " number of oscillations in a given period of time ".
