Question

What is the amplitude and wavelength of the wave?

Answer 1

Answer:

The amplitude is  $A = 5 \ cm$

The wavelength is  $\lambda =30 \ m$

Explanation:

From the question we see that

  The maximum value is  $b = 5 \ cm$

   The minimum value is  $a = -5 \ cm$

         

Generally the amplitude is mathematically represented as

       $A = \frac{1}{ 2} * [b - a ]$

=>     $A = \frac{1}{ 2} * [5 -(- 5) ]$

=>     $A = 5 \ cm$

Gnerally the wavelength is the distance between the to adjacent trough and from the diagram it is  

        $\lambda =[ 40 + [ \frac{45- 40 }{2} ]] -[ 10 + [\frac{15- 10 }{2} ] ]$

=>     $\lambda =30 \ m$
