The wavelength is 2m.
Hence, Option c) 2m is the correct answer
Given that;
Frequency; [tex]f = 30Hz[/tex]
Speed; [tex]v = 60m/s[/tex]
Wavelength; [tex]\lambda =\ ?[/tex]
using the expression for the relations between wavelength, frequency and speed of wave:
[tex]\lambda = \frac{v}{f}[/tex]
Where [tex]\lambda[/tex] is wavelength, f is frequency and v is speed.
We substitute our given values into the equation
[tex]\lambda = \frac{60m/s}{30Hz}\\\\\lambda = \frac{60m/s}{30s^{-1}}\\\\\lambda = 2m[/tex]
The wavelength is 2m.
Hence, Option c) 2m is the correct answer.
