The wavelength of a sound wave or any other wave is given by the formula:
wavelength = speed of wave / frequency
For a sound wave in air, the speed of sound is approximately 343 meters per second at room temperature.
If we consider a sound wave with a frequency of 1 Hz, we can calculate its wavelength as follows:
wavelength = 343 m/s / 1 Hz
The wavelength of a 1 Hz sound wave in air is approximately 343 meters.
