What is the wavelength of a 20 Hz periodic wave moving at 40 m\s? Please
The wavelength of a wave can be calculated using the formula:
wavelength = speed of the wave / frequency
Given that the speed of the wave is 40 m/s and the frequency is 20 Hz:
wavelength = 40 m/s / 20 Hz = 2 m
Therefore, the wavelength of the 20 Hz periodic wave moving at 40 m/s is 2 meters.
