Question

What is the unit for frequency?

Answer 1

Answer:

Hertz

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 :

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

$\nu$ is the frequency of a wave  

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

The SI unit of T is second (s). So, the SI unit of frequency is $s^{-1}$ or Hertz. So, the unit of frequency is Hertz.
