Answer:
To calculate the speed of waves, we need to know the frequency of the waves. The speed of waves is given by the formula:
Speed (v) = Frequency (f) × Wavelength (λ)
Given that the distance between wave crests (wavelength, λ) is 1.3 meters, we still need the frequency (f) to find the speed.
If you have the frequency of the waves, please provide that information, and I can help you calculate the speed. If not, without knowing the frequency, we cannot determine the speed of the waves.
