A sound source of frequency $170 \mathrm{Hz}$ is placed near a wall. A man walking from the source towards the wall finds that there is a periodic rise and fall of sound intensity. If the speed of sound in air is $340 {\mathrm{ms}}^{-1}$, the distance (in metre) separating the two adjacent positions of minimum intensity is:
