Final answer:
The speed of the wave can be calculated by multiplying its frequency by its wavelength. In this case, the speed of the wave is 42 m/s.
Step-by-step explanation:
The speed of a wave can be calculated by multiplying its frequency by its wavelength. In this case, the wave has a frequency of 14 Hz and a wavelength of 3 meters. So, the speed of the wave can be calculated as:
Speed = Frequency x Wavelength
Speed = 14 Hz x 3 m = 42 m/s
Therefore, the correct answer is A) 42 m/s.
The derived speed of 42 m/s signifies the rate at which the wave propagates through the medium, underscoring the importance of understanding the interplay between frequency and wavelength in determining wave characteristics.
