wof: wavelength and frequency

In bioSNR: Bioacoustic Basic Operations with Decibels and the Passive Sonar Equation

wavelength and frequency

Description

This function finds the length of a sound wave, known as the wavelength (m), or frequency of a sound (Hz), given the identity of the input. The speed of sound is the default in air (340 m/s). You may calculate your own value for c relative to the conditions present in your ecosystem of study via soundSpeed().

Usage

wof(b, c = 340)

Arguments

b	The known wavelength (m) or frequency (Hz).
c	The speed of sound in m/s. As a general rule of thumb, however, c is equal to 1500 m/s in saltwater and 350 m/s in air. Note that the distinction between freshwater and saltwater is important. Sound speed is faster in saltwater than freshwater.

Value

The unknown wavelength (m) or frequency (Hz) given the identity of input a.

Examples

# Given a frequency of 80 Hz in air, what is the wavelength?
wof(80000)
# Given a wavelength of 0.004 m in salt water, what is the frequency?
wof(0.004, c=1500)
