Awave has a period of 1. What is its frequency?

Andrei [34K]

Answer:

Frequency, f = 1 unit

Explanation:

It is given that,

Period of the wave, T = 1 unit

We need to find the frequency of the wave. There exist an inverse relationship between period and the frequency of the wave. It is given by :

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

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

$f=\dfrac{1}{1\ units}$

f = 1 unit

So, the frequency of the wave is 1 unit. Hence, this is the required solution.
