Hello!!
For this, we only need frequency and speed, so for calculate we applicate formula:
[tex]\boxed{\lambda = V/f}[/tex]
[tex]\textbf{Being:}[/tex]
[tex]\sqrt{}[/tex] [tex]\lambda = Wavelength = \ ?[/tex]
[tex]\sqrt{}[/tex] [tex]V = Velocity = 2.998*10^{8} \ m/s[/tex]
[tex]\sqrt{}[/tex] [tex]f = Frequency = 9,650*10^{7} \ Hz[/tex]
[tex]\text{Then let's \textbf{replace it according} we information:}[/tex]
[tex]\lambda = 2,998*10^{8} \ m /s / 9,650*10^{7} \ Hz[/tex]
[tex]\lambda = 3.106 \ m[/tex]
[tex]\textbf{Result:}\\\text{The wavelength of the radiowave is \textbf{3.106 meters}}[/tex]
