The image displays a physics problem labeled as number 5. The layout consists of a paragraph of text at the top, a diagram in the center, and a block of text with a specific question at the bottom.

At the very top, the text reads: "5. Your roommate calls you in a panic. He's just started his internship as an archaeologist at an Ancient Castle down the street, and upon opening a vault that even time has long since forgotten, he found the following apparatus, composed of four hollow tubes (of identical diameter), a hammer, and a little bench that they're all sitting on."

Below this text is a line drawing of the apparatus. It features a rectangular base or bench. Standing vertically out of this bench are four hollow cylinders or tubes. From left to right, the tubes are labeled with capital letters inside them: D, C, B, and A.
- The tube labeled "D" is on the far left. It is tall.
- Next to it is a shorter tube labeled "C". This appears to be the shortest of the four.
- To the right of C is the tallest tube, labeled "B".
- On the far right is a tube labeled "A", which is taller than C but shorter than D and B.

To the left of the tubes, there is an object shaped like a T, representing a hammer, with the label "Hammer" inside a box next to it.

Inside the rectangular base of the bench, there are two square compartments side-by-side.
- The compartment on the left contains the word "Treasure".
- The compartment on the right contains the words "Ancient Evils".

Below the diagram, there is a section introduced by the text: "Below the apparatus (which is drawn to scale) is the following inscription:" followed by italicized text that reads: "Foolish traveler, beware. To access the treasure, you must whack each tube with the hammer to produce a note (much like a xylophone or marimba). But you must be careful to hit the tubes in the order of lowest pitched note to highest pitch note, or instead of getting treasure, you'll release ancient, vowel-hating evils into the world that will destroy communication all through the world. So, be careful, and remember: Lowest pitch to highest pitch."

At the very bottom is question (a), which reads: "(a) Knowing what you now know about resonances in tubes, which order would you want to hit the tubes in in order to go from lowest frequency of resonance to highest frequency of resonance, thus giving you the treasure and avoiding the ancient evils? (5 points)"
