The speed of a wave can be calculated using the formula:
Speed (v) = Wavelength (λ) × Frequency (f)
Given that the wavelength (λ) is 2.5 meters and the frequency (f) is 6 Hz, we can substitute these values into the formula:
v = 2.5 m × 6 Hz
Calculating the product:
v = 15 m/s
Therefore, the speed of the wave is 15 meters per second.
