Question
Is mayonnaise an instrument? Maybe, but an empty mayonnaise bottle is definitely an instrument because when you blow air over the opening, it makes a sound. For 10 points each:
[10e] Sound constitutes one of these phenomena inside the bottle, for which the amplitude profile does not move in space. Places where the absolute value of the amplitude is at a minimum are the nodes of these phenomena.
ANSWER: standing waves [prompt on “waves”]
[10m] With the cap off, a mayonnaise bottle can be modeled as an open-closed tube, for which this quantity is equal to the speed of sound over 4 times the length of the bottle. This quantity is the first harmonic of an instrument.
ANSWER: fundamental frequency [or fundamentals; prompt on “frequency”]
[10h] This apparatus measures the speed of sound by applying a pure tone and adjusting the length of the bottle until the sound resonates. It calculates the speed of sound using the distance between piles of powder.
ANSWER: Kundt’s tube
