A cylindricаl pipe, clоsed аt bоth ends, cоntаins air molecules, where the speed of sound is [v] m/s. When the pipe resonates, it forms a standing sound wave inside. The figure shows a snapshot of the standing wave with a wavelength of [lamda] m. When the air in the pipe resonates at its fundamental frequency, calculate the fundamental frequency in hertz (Hz).
