The wave velocity can be determined by multiplying the frequency (f) of the wave by its wavelength (λ). The formula for wave velocity (v) is:
v = f × λ
Given that the frequency (f) is 1 Hz and the wavelength (λ) is 2 m, we can substitute these values into the formula:
v = 1 Hz × 2 m v = 2 m/s
Therefore, the wave velocity in this case is 2 meters per second (m/s).
