What is the length of a 40hz soundwave?

The wavelength of a sound wave can be calculated using the formula ( \text{Wavelength} = \frac{v}{f} ), where ( v ) is the speed of sound in air (approximately 343 meters per second at room temperature) and ( f ) is the frequency. For a 40 Hz sound wave, the wavelength would be ( \frac{343 , \text{m/s}}{40 , \text{Hz}} ), which equals about 8.575 meters. Therefore, the length of a 40 Hz sound wave is approximately 8.58 meters.
