The given numerical data mention the length of the spring l. They say nothing at all about the distance between the walls, 2L. It could be zero for all we know... Or 20 meter. That's why I don't like the formulation of the exercise.
ehild: yes for D << L I can follow ## \ ω^2=\frac{3g}{D}\ ##: in your picture L < l (lower case l, that is).
Is it also obvious that ##\ ω^2 \rightarrow \frac{g}{D}\ ## for L ##\downarrow## 0 ? (l stays 0.5).
