Let me clarify:
Wavelength is not a physical property of a sound wave itself, but rather a property of the medium through which the sound wave propagates. It represents the physical distance between two consecutive points in a wave that are in phase with each other, such as two adjacent peaks or two adjacent troughs of the wave. In the context of sound waves, it refers to the distance between two points of maximum compression or rarefaction.
To be more precise, wavelength represents the spatial period of the wave, meaning the distance it takes for one complete cycle of the wave to occur. It is measured in physical units such as meters (m) or centimeters (cm).
Frequency, on the other hand, is a characteristic of the sound wave itself and represents the number of complete oscillations or cycles of the wave that occur in a given time period. It is measured in hertz (Hz), where 1 Hz equals one cycle per second.
The relationship between wavelength and frequency is as follows:
Wavelength (λ) = Speed of sound (c) / Frequency (f)
In the case of sound waves, the speed of sound in a given medium is relatively constant, so as the frequency of the wave increases, the wavelength decreases, and vice versa.
To summarize, while wavelength is not a physical property of the sound wave itself, it represents the distance between two points in the wave, and frequency represents the number of oscillations or cycles of the wave occurring per unit of time.
