Two small speakers are driven by a common oscillator at $8\mathrm{.}10102$ Hz$.$ The speakers face each other and are separated by

d $=1\mathrm{.}06$ m$.$

Locate the points along a line joining the two speakers where relative minima would be expected. $($Use v $=343$ m$/$s$.$ Choose one speaker as a reference and enter your answers as positive distances from this speaker, from smallest to largest. Enter NONE in unused answer boxes.$)$
