A trailer truck traveling east at 38 m/s sounds a 1300 Hz horn. what is the wavelength stationary listener west?

The wavelength of a stationary listener is 0.029 m.

The given parameters;

The wavelength of a stationary listener is calculated as follows;

where;

λ is the wavelength of the sound wave

The value of the wavelength is determined as;

Thus, the wavelength of a stationary listener is 0.029 m.

Explanation:

The velocity of sound wave is expressed using the formula;

where

f is the frequency

is the wavelength

Given

f = 1300Hz

v = 38m/s

Required

wavelength

From the formula;

= v/f

= 38/1300

= 0.0292m

Hence the required value of the wavelength is 0.0292m

0.863333
