speed of a wave, v, is equal to the wavelength multiplied by the frequency.

Therefore

v= 3 x 0.1 = 0.3 ms^-1

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.
