Question 24 (3 points) In a classroom demonstration, saw dust is placed in a tube and the tube is sealed at both ends. A speaker sends a monotonic sound wave into the tube causing the air and saw dust to vibrate. At proper frequencies, standing waves are observed as shown in the images below. If the middle image is created by a sound wave of 200 Hz, what is the frequency of sound wave used to create the top image?
