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...
