which of the following properties of a sound wave determines its pitch: wavelength, speed, amplitude, or frequency?
Plese show work,
Thank you,
Silly
frequency: low frequency = low pitch
high frequency = high pitch
To determine the pitch of a sound wave, we need to identify the property that is responsible for it.
Pitch refers to how high or low a sound is perceived. It is directly related to the frequency of a sound wave. Frequency is the number of complete cycles or vibrations of a sound wave occurring in one second.
To find the answer, we need to identify which property in the given options is related to frequency. In this case, the correct answer is frequency.
To understand why, let's look at the other properties:
- Wavelength: Wavelength is the length of one complete cycle of a sound wave. It is inversely related to frequency, meaning that as the wavelength increases, the frequency decreases, and vice versa. However, wavelength alone does not determine the pitch of a sound wave.
- Speed: Speed refers to how quickly a sound wave travels through a medium. It is determined by the properties of the medium itself and is not directly related to pitch.
- Amplitude: Amplitude refers to the intensity or loudness of a sound wave. It describes the maximum displacement of particles in the medium from their rest position. Although amplitude does influence how loud a sound is, it does not determine the pitch.
Therefore, the correct property that determines the pitch of a sound wave is its frequency.
To find this answer yourself, you can use knowledge of the properties of sound waves and their characteristics. Additionally, you can consult sources such as physics textbooks, educational websites, or ask subject matter experts for more information.
