Formula:

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

v = f * λ

Given:

* Frequency (f) = 10 kHz = 10,000 Hz

* Wavelength (λ) = 2 m

Calculation:

v = (10,000 Hz) * (2 m)

v = 20,000 m/s

Answer:

The speed of the wave is 20,000 meters per second.
