Question

A wave hits The Beach every 10 seconds whats its frequency?

Please Help!

A 0.10 Hz

B 1.0 Hz

C 10.0 Hz

D 100.0 Hz

Answer 1

The frequency of the wave is 0.10 Hz

Step-by-step explanation:

Number of vibrations or number of waves per unit time is called frequency. The SI unit of frequency is Hz. It is given by the equation

In this question time = 10 seconds

number of waves = 1

`frequency= \frac {number of waves} {time interval} = \frac {1}{10} = 0.10 Hz`

Frequency is a characteristic feature of waves. Other characteristics of a wave are time period, amplitude etc. Time period is the time taken for one complete vibration and frequency is obtained by taking the reciprocal of time period.
