The Formula

The velocity of a wave is calculated using the following formula:

* Velocity (v) = Frequency (f) × Wavelength (λ)

Applying the Formula

1. Frequency (f): 10 Hz

2. Wavelength (λ): 2 m

Calculation:

* v = 10 Hz × 2 m

* v = 20 m/s

Answer: The velocity of the wave is 20 meters per second (m/s).
