The speed of sound in air is given as 340 m/s, and the frequency of the sound emitted by the source is 180 Hz. To calculate the wavelength of the sound, we can use the formula:
wavelength = speed of sound / frequency
Plugging in the values:
wavelength = 340 m/s / 180 Hz
wavelength = 1.89 meters (rounded to two decimal places)
Therefore, the wavelength of the sound between the source and the listener is approximately 1.89 meters.
