4 16- 1. Prepare for lectures • attempt assigned reading before class • be active in class ( paying attention to lecture is more important than taking exacting notes ) 1. Come to lecture • ¼ of class time spent solving problems 3. Do homework • best way to prepare for exam is by doing problems 4. Don’t fall behind! Cover 1 Chap/week! 5. If you have questions, get them answered 6. Discuss and explore material with classmates Come to office hours when you need help Recipe for Success in Physics 207

6 16- Why learn about waves? 1. Fundamental, quantitative, and creative thinking what you learn Physics 207 will make you a better scientist or engineer 1. Fundamental to classical and modern physics How does your TV/radio function? How do telescopes and microscopes work? Why don’t hydrogen atoms and neutron stars implode? 1. Material is interesting and exciting (of course…!)! Motivation

7 16- Waves: • mechanical (sound, water, etc.) • non-mechanical (EM) continuation of Physics 108 • optics • quantum mechanics: electron, photon, hydrogen atom • Schroedinger’s wave equation • Pauli principle • Periodic table • Optical properties of materials • Lasers z(x,t) x or t A wave is an organized oscillation causing a displacement in z (position, pressure, temperature, electric field, density, etc) as a function of x or t

9 Mechanical waves: require a material medium (water, air, rock, string) Electromagnetic waves: visible and invisible light ( x-rays , ultraviolet light , visible light, microwaves , radar waves , radio and TV waves ,). Travels in vacuum at speed c = 299,792,458 m/s. Matter waves: small particles (electrons, protons, etc) can behave like waves quantum mechanics Types of Waves 16-
