Which of the following statements incorrectly describes a scenario where the source of the sound waves and the person hearing the sound are remaining stationary?
To find the incorrect statement, we need to analyze each statement individually and determine if it accurately describes a scenario where the source of the sound waves and the person hearing the sound are remaining stationary.
Statement 1: "A person hears the sound of a bell ringing from a distant church."
In this scenario, both the source of the sound waves (the bell in the church) and the person hearing the sound (the listener) are stationary. This statement correctly describes a scenario where both the source and the person hearing the sound are remaining stationary.
Statement 2: "A person hears the sound of a speeding car passing by."
In this scenario, the source of the sound waves (the speeding car) is moving, while the person hearing the sound (the listener) is stationary. This statement correctly describes a scenario where the source of the sound is in motion, but the person hearing the sound is stationary.
Statement 3: "A person hears the sound of an airplane flying overhead."
In this scenario, the source of the sound waves (the airplane) is moving, while the person hearing the sound (the listener) is stationary. This statement correctly describes a scenario where the source of the sound is in motion, but the person hearing the sound is stationary.
Statement 4: "A person hears the sound of a TV show playing on a TV at home."
In this scenario, both the source of the sound waves (the TV playing the show) and the person hearing the sound (the listener) are stationary. This statement correctly describes a scenario where both the source and the person hearing the sound are remaining stationary.
Since all the statements correctly describe scenarios where either the source or the person hearing the sound (or both) are remaining stationary, none of the statements incorrectly describes such a scenario.
In a scenario where the source of the sound waves and the person hearing the sound are remaining stationary, the following statement incorrectly describes that scenario:
"There will be a noticeable change in the pitch of the sound as the source moves away from the listener."
This statement is incorrect because, in a stationary scenario, where both the source and the listener are not moving, there will not be any change in the pitch of the sound. The sound waves will travel directly from the source to the listener without any Doppler shift occurring. The pitch remains constant throughout the observation.
