To determine the speed of the wave, you can use the equation:
v = f * λ
where: v is the speed of the wave, f is the frequency of the wave, and λ is the wavelength of the wave.
Given that the frequency (f) is 10 Hz and the wavelength (λ) is 30 m, you can substitute these values into the equation:
v = 10 Hz * 30 m v = 300 m/s
Therefore, the speed of the wave is 300 meters per second.
