Question

What is the amplitude and wavelength of the wave?

Answer 1

The amplitude is
`A = 5 \ cm`

The wavelength is
`\lambda =30 \ m`

Step-by-step 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 = (1)/( 2) * [b - a ]`

=>
`A = (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 + [ (45- 40 )/(2) ]] -[ 10 + [(15- 10 )/(2) ] ]`

=>
`\lambda =30 \ m`
