The length of a sound wave, also known as its wavelength, depends on the frequency of the sound. In general, the wavelength of a sound wave can range from very short distances to extremely long distances. The wavelength is determined by dividing the speed of sound in a particular medium by the frequency of the sound.
In a typical atmospheric environment at sea level, the speed of sound is approximately 343 meters per second (or 1,125 feet per second). Using this speed as a reference, we can calculate the wavelength for different frequencies. For example, a sound wave with a frequency of 20 hertz (Hz) would have a wavelength of approximately 17 meters (56 feet), while a sound wave with a frequency of 20,000 Hz (20 kilohertz) would have a wavelength of approximately 17 millimeters (0.67 inches).
It's important to note that in different media, such as water or solids, the speed of sound can vary, which would affect the wavelength of the sound wave accordingly. Additionally, in practical terms, sound waves can propagate over long distances in the atmosphere or other media, but they eventually become very weak and difficult to detect as they disperse and interact with the surrounding environment.
