Answer : Speed, v = 0.3 m/s
Explanation :
It is given that,
Wavelength of the wave, [tex]\lambda=3\ m[/tex]
Frequency of the wave, [tex]f=0.1\ Hz[/tex]
We know that the speed of the wave is given as :
[tex]v=f\times \lambda[/tex]
[tex]v=0.1\ Hz \times3\ m[/tex]
[tex]v=0.3\ m/s[/tex]
So, the correct option is (b) " 0.3 m/s".
Hence, this is the required solution.
