Respuesta :
The speed of the wave will be "80 m/s".
Given values are:
- Frequency, f = 2
- Wavelength, λ = 40
The speed of the wave:
→ [tex]Speed = Frequency\times wavelength[/tex]
or,
→ [tex]v = f\times \lambda[/tex]
By putting the values, we get
[tex]= 2\times 40[/tex]
[tex]= 80 \ m/s[/tex]
Thus the solution above is correct.
