In ... many science fiction movies, an evil alien spaceship explodes with an enormous KABOOM!! Suppose you were floating in space at a safe distance from a large explosion such as the supernova at left. Do you think you would you hear anything? Explain. No, I don’t think I would hear anything because there is the vacuum of space and the sound would basically not be able to travel through that medium. Gizmo Warm-up No sounds can be heard in outer space because sound waves require a medium, such as air, to travel through. Sound waves are examples of longitudinal waves, or waves in which particles move back and forth in the same direction as the wave. You can use the Longitudinal Waves Gizmo™ to explore the behavior of sound waves. In the Gizmo, an air-filled tube contains 24 evenly-spaced, airtight dividers. To begin, select the Pulsed waves setting and the Open tube. Set the Strength to 1.00. Deselect the graph options at lower right. 1. Click Play ( ) to set off the firecracker by the left end of the tube. What do you see? I see the wave travel from left to right, and there is compressions and I watched the amplitude change too when it came back from right to left. 2. Do any individual air molecules travel the length of the tube? Yes How do you know? Because the dividers don’t prevent the air molecules from entering or leaving [Show More]
