2019 #5 Free Response Question - AP Physics 1 - Exam Solution

The video tutorial covers question #5 from the 2019 AP Physics One exam, focusing on a tuning fork vibrating at 512 Hz near a tube open at both ends. The tutorial explains how to calculate the tube's length when resonating at its fundamental frequency, graph the maximum speed of air molecules, and determine the new fundamental frequency when the tube is closed at one end and placed in a different gas. The video emphasizes understanding wave patterns, displacement nodes, and anti-nodes, and provides guidance on graphing and calculations.

Illustrate the relationship between frequency, speed, and wavelength in the context of this problem.

Discuss the scoring guidelines for sketching the graph of maximum particle speed in the tube.

How does the speed of sound in a different gas affect the fundamental frequency of the tube?
