Calculate the acoustic wavenumber (\(k\)) for a given frequency and sound speed.

Calculates the acoustic wavenumber (\(k\)) for a given frequency and sound speed in water. The wavenumber is defined as: $$k = \frac{2\pi f}{c}$$ where \(f\) is the frequency (Hz) and \(c\) is the sound speed (\(ms^{-1}\)). The wavenumber describes the spatial frequency of a sound wave and is fundamental in acoustic calculations.

Usage

wavenumber(frequency, sound_speed)

Arguments

frequency

Frequency (f, Hz)

sound_speed

Sound speed (c, \(m~s^{-1}\))

Value

Calculates the acoustic wavenumber (k) based on the sound speed of water.
