Unformatted text preview: Chapter 16 The Quantum Model of the Atom Did you read all of Chap. 16 for today? a) Yes b) No Quiz: How did the reading go? ) nderstood everything wanted a) Understood everything wanted more b) OK, but have questions c) Not so well—but understood that they were talking about a new model of the atom d) And I thought “LOST” was just a TV show Earth Perspective fast Relativity large small slow Newton’s Laws ok Wave-Particle Duality Question? Standing waves are created when waves reflect and bounce back to where they started from. Think of a violin string. BUT, can they be created on a round surface? a) Yes b) No Go check out the Wave-a-Tron in ESC Standing Waves s Recall we created standing waves using a jigsaw and stretching a stretching band. • Tacoma Narrows Bridge. 2 Dimensions s It is easy to create standing waves in 2 dimensions as well. A single wave on a drum head Two waves on a drum head Three waves on a drum head 3 Dimensions s Standing waves can be set up inside the cavities of musical instruments as well. he patterns trace the • The patterns trace the nodes and antinodes on the violin back. Wrap standing waves around a point s These are patterns of vibration. One wave Two waves Three waves Bohr Model Explained! s Take deBroglie’s waves and wrap them in a standing wave pattern around the nucleus. s Put one wavelength , then two, then three, etc. and you exactly predict the location of the Bohr radii!...
