The formula to calculate the frequency of a wave is:
frequency = speed / wavelength
So in this case, the frequency would be:
frequency = 400 m/s / 10 m = 40 Hz
Therefore, the correct answer is 40 Hz.
The speed of a wave is 400 m/s and its wavelength is 10 meters. What is the frequency of the wave?
4 Hz
0.4 Hz
40 Hz
4000 Hz
