Answer:
The wavelength of wave is 2.78 m.
Explanation:
Frequency of a wave is 90 Hz
Speed of a wave is 250 m/s
It is assume to find the wavelength of wave. The formula of speed is given by :
[tex]v=f\lambda\\\\\lambda=\dfrac{v}{f}\\\\\lambda=\dfrac{250}{90}\\\\\lambda=2.78\ m[/tex]
So, the wavelength of wave is 2.78 m.
