Formula:

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

v = fλ

Where:

* v = velocity (meters per second, m/s)

* f = frequency (Hertz, Hz)

* λ = wavelength (meters, m)

Calculation:

* f = 10 Hz

* λ = 2 m

v = 10 Hz * 2 m

v = 20 m/s

Answer:

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