Waves are everywhere! Spiders detect prey by the vibrations of their webs, cars oscillate up and down when they hit a bump, buildings and bridges vibrate when heavy trucks pass or the wind is fierce. Electrical oscillations occur in radio and television sets. At the atomic level, atoms vibrate within a molecule, and the atoms of a solid vibrate about their relatively fixed positions.
Vibrations and wave motion are intimately related subjects. Waves whether ocean waves, waves on a string, earthquake waves, or sound waves in airhave as their source a vibration. In the case of sound, not only is the source a vibrating object, but so is the detectorthe eardrum or the membrane of a microphone. Indeed, the medium through which a wave travels itself vibrates (such as air for sound waves).
In this PhysicsQuest you will learn about the nature and properties of waves. You will see how waves behave at boundaries and how standing waves are formed.
You will read each section and answer the questions given.
