Final answer:
The velocity of a wave with a wavelength of 0.5 meters and a frequency of 100 Hz is calculated using the formula Vw = fλ to be 50 meters per second.
Step-by-step explanation:
To find the velocity of a wave, you can use the formula Vw = fλ, where Vw represents the wave velocity, f is the frequency of the wave, and λ is the wavelength. Given that the wave has a wavelength of 0.5 meters and a frequency of 100 Hz, you would calculate the velocity as follows:
Vw = fλ = 100 Hz × 0.5 m = 50 m/s.
Therefore, the velocity of the wave is 50 meters per second (50 m/s).
