You stand on a pier watching water waves and see 10.9 waves pass by in a time of 28 seconds. What is the frequency of the water waves?

Respuesta :

Answer:

0.4Hz

Explanation:

Given parameters:

   Number of waves  = 10.9waves

   Time taken  = 28s

Unknown:

Frequency of water waves = ?

Solution:

The frequency of a wave is the number of waves that passes through a point per unit of time.

  Frequency  = [tex]\frac{number of waves }{time}[/tex]

  Insert parameters and solve;

         Frequency  = [tex]\frac{10.9}{28}[/tex]   = 0.4Hz
