Audible wavelengths. the range of audible frequencies is from about 20.0 hz to 2.00×104 hz . what is range of the wavelengths of audible sound in air?

The range of the wavelengths of audible sound in air is from about 0.0172 m to 17.2 m

Let's recall the speed of wave and intensity of wave formula as follows:

f = frequency of wave ( Hz )

v = speed of wave ( m/s )

λ = wavelength ( m )

I = intensity of wave ( W/m² )

A = amplitude of wave ( m )

f = frequeny of wave ( Hz )

ρ = density of medium ( kg/m³ )

v = speed of wave ( m/s )

Let's tackle the problem!

Given:

minimum frequency = f_min = 20.0 Hz

maximum frequency = f_max = 2.00 × 10⁴ Hz

speed of sound in air = 343 m/s ( assumption )

Asked:

minimum wavelength = λ_min = ?

maximum wavelength = λ_max = ?
