Answer:
The correct option is (b) i.e. 0.03 m.
Explanation:
We have,
Speed of a wave is 0.09 m/s and the frequency of a wave is 3 Hz.
It is required to find the wavelength of a wave.
The speed of a wave in terms of wavelength and frequency is given by :
[tex]v=f\lambda\\\\\lambda=\dfrac{v}{f}\\\\\lambda=\dfrac{0.09}{3} \\\\\lambda=0.03\ m[/tex]
So, the wavelength of a wave is 0.03 m.
