In the diagram, a tuning fork is positioned above an air column that has a length of $25\,\text{cm}$. A stationary wave forms in the tube at the same frequency as the tuning fork. The bottom of the tube is closed. This is the shortest tube length, with the bottom closed, that produces a stationary wave. Which other tube lengths, with their lower ends sealed, will also produce a stationary wave?
- A$37.5\,\text{cm}$ and $50\,\text{cm}$
- B$50\,\text{cm}$ and $75\,\text{cm}$
- C$75\,\text{cm}$ and $100\,\text{cm}$
- D$75\,\text{cm}$ and $125\,\text{cm}$
