Understanding the Relationship

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

* v = λf

Applying the Formula

1. Convert wavelength to meters: 18 cm = 0.18 meters

2. Plug in the values:

* v = (0.18 m) * (1900 Hz)

3. Calculate the speed:

* v = 342 m/s

Therefore, the speed of the sound wave is 342 meters per second.
