Student Exploration: Longitudinal Waves Prior Knowledge Questions ​(Do these BEFORE using the Gizmo.) 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. I don’t think so, I think the sound doesn’t have anything to vibrate to make the noise in space. 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​TM​ 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 rig [Show More]
