Plasma frequency squared is scanned across exact density and mass ratios. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.

highlighted = computed this step

The checked oscillation square starts from a ratio

The diagram pins normalized constant twelve, density ratio three, and mass ratio six. The square frequency is therefore six.

Density and mass ratio pull opposite directions

The first row is the checked source. Doubling density doubles omega squared; halving mass ratio doubles it again.

The square frequency follows density over mass

The lesson stays with omega squared so every row remains exact. That is enough to see the collective frequency trend.
