Question

5 waves in 20 seconds what is the frequency?

Answer 1

0.25 Hz (Hertz).

Step-by-step explanation:

To calculate the frequency of a wave, you can use the formula:

Frequency (f) = Number of Waves / Time

In your case, you have 5 waves in 20 seconds:

Frequency (f) = 5 waves / 20 seconds = 0.25 waves per second

So, the frequency is 0.25 Hz (Hertz).
