Answer:
.378787878 m =Wavelength
Step-by-step explanation:
The formula to find the speed of a wave is found by
Speed = Wavelength x Frequency where the frequency is in HZ and the wavelength is in meters
250 = Wavelength*660
Divide each side by 660
250/660 = Wavelength*660/660
.378787878 m =Wavelength
