Answer:
The amplitude is
The wavelength is

Step-by-step explanation:
From the question we see that
The maximum value is

The minimum value is

Generally the amplitude is mathematically represented as
![A = (1)/( 2) * [b - a ]](https://img.qammunity.org/2021/formulas/physics/high-school/cyqe63tlv9794euce3f8n26arw1phbcv0s.png)
=>
![A = (1)/( 2) * [5 -(- 5) ]](https://img.qammunity.org/2021/formulas/physics/high-school/m11rm8erhu2kjgmpry555y584db1q7o49o.png)
=>

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) ] ]](https://img.qammunity.org/2021/formulas/physics/high-school/n9u4a940xsjm3avbnkvaj722uwkz3adjco.png)
