Let us Fig. traversed by take on AM the lengths A A, AA, A point A in the time which each simple oscillation takes toaccomplish. When the point A is at A, the rod will be atAD at the end of its first simple oscillation ; in the same waythe rod will terminate its second, oscillation in thepositions AC, These positions are very near those•which correspond to minima of velocity; the other positionsare traversed very rapidly, and it is on this account that imagesof the rod are distinctly seen nearly in the positions AC, AD,AC, AD They will be seen simultaneously if the move-ment of translation is suitable.
