Answer : The speed of waves along the wire is, 1.2 m/s
Explanation :
Formula used :
[tex]\nu=\frac{c}{\lambda}[/tex]
where,
[tex]\nu[/tex] = frequency = [tex]4.00Hz=4.00s^{-1}[/tex]
[tex]\lambda[/tex] = wavelength = [tex]30.0cm=0.3m[/tex]
c = speed of wave = ?
Now put all the given value in the above formula, we get the speed of waves along the wire.
[tex]4.00s^{-1}=\frac{c}{0.3m}[/tex]
[tex]c=1.2m/s[/tex]
Thus, the speed of waves along the wire is, 1.2 m/s
