Answer:
4 m/s
Step-by-step explanation:
The speed of a wave can be calculated using the formula speed = frequency * wavelength.
Given that the frequency of the wave is 0.5 Hz and the wavelength is 8 meters, we can calculate the speed as follows:
speed = frequency * wavelength
speed = 0.5 Hz * 8 meters
speed = 4 m/s.
