Answer:
2028 m/s
Explanation:
Velocity of a wave is given as the product of frequency and wavelength and expressed as
V=fw
Where V denote the velocity, f is frequency while w is walength.
Note that the speed of wave does not depend on amplitude. Therefore, we don't need it for calculation of velocity in this question.
Substituting 390 Hz for f and 5.2 m for wavelength then the velocity is given as
V=390*5.2=2028 m/s
