Final answer:
The period of the wave is 0.07 seconds.
Step-by-step explanation:
The period of a wave can be calculated using the formula:
Period (T) = Wavelength (λ) / Velocity (v)
Substituting the given values, we have:
Period (T) = 3.5 m / 50 m/s = 0.07 s
Therefore, the period of the wave is 0.07 seconds.
