Unformatted text preview: Physics 214 Waves and Quantum Physics Welcome to Physics 214 Welcome to Physics 214 Content: Waves and Quantum Physics • Format: Active Learning (Learn from Participation) • Textbook – Young and Freedman -- Assignments on Syllabus page c Lectures (presentations, demonstrations, & ACTs) c Discussion Sections (group problem solving) -- start this week c Labs (hands-on interactions with the phenomena) -- Submit Prelab to instructor at 1st session (next week) Bring your calculator! Ask the Professor (from the Homepage) : An opportunity for you to get answers in lecture to your questions. This Thursday only : 2 bonus points for filling in the “Ask the Professor” survey. James Scholar Students : Email [email protected] within 1 week. *Note: Make sure you do not have a lab or discussion section before your Tuesday lecture. WWW and Grading Policy WWW and Grading Policy c This course makes extensive use of the World-Wide-Web c http://online.physics.uiuc.edu/courses/phys214 c Here you will find general course announcements, the course syllabus, the course description & information, the lecture slides, lab information, the homework assignments (which you will actually submit to be graded on the Web), sample exams, and the official gradebook. c Faculty: Lectures: Paul Debevec & Richard Martin Labs: Bob Clegg Discussion: Mike Weissman c Grading Policy c see Course Description on Web for CAREFUL STATEMENT !! c Your final grade for Physics 214 will be based your total score: c final exam (350 pts), c midterm exam (200 pts), c four labs (150 pts total), Begin in Week 2. Prelabs due then. c six homeworks (150 pts total), and c five quizzes (highest four = 150 pts total) c Rough guidelines for letter grade minima are: c A+(960) A(935) A-(910) c B+(885) B(855) B-(830) c C+(800) C(770) C-(740) c D+(700) D(660) D-(620) F(<620) c Interferometers c Precise distance and rotation measurements c Noninvasive microscopy c Search for gravitational waves – LIGO! What is 214 all about?(1) What is 214 all about?(1) c Many physical phenomena of great practical interest to engineers, chemists, biologists, physicists, etc. were not in 211+212. c Wave phenomena (made of old ingredients) c Interference: what happens when you add waves? c e.g., light + light = no light ???? c Diffraction: c Optical Spectroscopy - diffraction gratings c Optical Resolution - diffraction-limited performance of lenses,… Interference! c Quantum Physics (starting from new principles) c All particles act like waves b only certain energies allowed in atoms (explains emission spectra of elemental gases (hydrogen, neon, etc.), molecules, and even solids and biological systems. What is 214 all about? (2) What is 214 all about? (2) c Quantum (cont.) c Novel nanometer-scale probes c The “wave-nature” of electrons, neutrons, etc., can be exploited in novel probes of materials, biological systems, etc. (e.g., electron and neutron scattering)....
