Question

What is the frequency of a wave

Answer 1

The frequency of a wave is the number of waves that passes through a point in a certain time. The less waves that pass in a period of time the lower the frequency of the wave. The more waves that pass in a period of time the higher the frequency of the wave. When measuring wave length the time period used is usually one second.

Answer 2

Explanation:

The frequency of a wave is defined as the number of vibrations or oscillations per unit time. It is also defined as the reciprocal of the time period. Its SI unit is hertz or s⁻¹.

Mathematically, it can be written as :

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

T is the time period of the wave.

The relation between the frequency and the wavelength is inverse. Also,

$\nu=\dfrac{v}{\lambda}$

The wave having higher frequency have higher energy and vice versa.

Hence, this is the required solution.
