The Relationship

The velocity (v) of a wave is related to its wavelength (λ) and frequency (f) by the following equation:

v = λf

Calculation

1. Given:

* Wavelength (λ) = 0.03 m

* Frequency (f) = 120 Hz

2. Substitute into the equation:

v = (0.03 m) * (120 Hz)

3. Calculate:

v = 3.6 m/s

Answer

The velocity of the wave is 3.6 meters per second (m/s).
