What range of sound wavelengths in air at room temperature are audible to a human with ideal hearing (f= 20 hz - 20 khz)?

0.017 m - 17 m

Explanation:

The relationship between wavelength and frequency of a wave is:

where v is the speed of the wave, the wavelength and f the frequency.

The speed of sound waves in air at room temperature is

v = 340 m/s

For the lowest frequency, f = 20 Hz, the wavelength is

For the highest frequency, f = 20 kHz = 20,000 Hz, the wavelength is

Answer;

A. A frame of reference that is moving at a constant velocity

Explanation;Special relativity is applied to reference frames that do no accelerate. If a reference frame moves with constant velocity relative to an inertial reference frame, it also is an inertial reference frame. There is no absolute inertial reference frame, meaning that there is no state of velocity which is special in the universe.Einstein's theories of relativity are a result of the contradiction between Newton's laws of motion and Maxwell's equations.
