Question

An observer sits in a boat watching wave fronts move past the boat. The distance between successive wave crests is 0.80 m, and they are moving at 2.6 m/s.What is the wavelength of these waves? What is the frequency of these waves? What is the period of these waves?

Answer 1

Answer:

The  wavelength is   $\lambda = 0.80 \ m$

The  frequency is  $f = 3.25 \ Hz$

Explanation:

From the question we are told that

     The distance between two successive crest is 0.80 m

      The  velocity is  v =  2.6 m/s

Generally wavelength is the distance between two successive crest

So  

    $\lambda = 0.80 \ m$

Now  the frequency is mathematically represented  as

        $f = \frac{v}{\lambda }$

        $f = \frac{2.6}{0.80 }$

       $f = 3.25 \ Hz$
