Course Contents
Electromagnetic and other Waves
The wave equation from Maxwell's equations and a review of general wave behavior. Poynting vector, polarization, refractive index, reflection and refraction.Geometrical and Physical Optics
Mirrors and refracting surfaces, thin lenses, images, and the eye. Interference, diffraction, coherence and resolving criteria.Special Relativity
Experiments on the speed of light. The principle of relativity, simultaneity, time dilation and length contraction. Lorentz transforms and velocity transformations. Various paradoxes, space-time diagrams and the Doppler effect. Relativistic momentum and energy, 4-vectors, co-moving frames and motion with constant acceleration.Introduction to Quantum Theory
Blackbody radiation, photoelectric effect, Compton scattering, de Broglie waves. Uncertainty principle, Experimental basis for atomic nuclei; hydrogen spectrum: Bohr model Schrodinger equation; complex amplitudes, probability interpretation; Stern-Gerlach experiment; basis for spin; bosons and fermions.Grading
There will be four exams: three exams throughout the semester and a final exam. Each exam will contribute 25% to the final grade with the lowest exam score dropped. The final exam will be a comprehensive exam. No make up exams will be offered. Exam scores will be 'renormalized' by adding (100-highest score) to each exam. 15% of the grade will be from homework assignments. 10% of the grade will be from iClicker quizzes and responses. No form of cheating will be tolerated. Grades will be determined using this grading scale.Homework
Homework assignments and due dates will be given in class and posted on this website. Assignments will be both Mastering Physics (MP) and written. Solutions to non-MP problem sets will be posted to this website. MP grading policy: no limit on attempts per question, no deduction for opening a hint. Credit is reduced 10% for each hour past the deadline. Incorrect answers give a 3% penalty or 100%/(number of answers) for T/F, multiple choice.iClicker quizzes and class participation
At the beginning of each class, one or two basic conceptual questions will be asked covering the material from the reading assignment. Responses to these 'quizzes' are credited 0/1/2 points for no/incorrect/correct answer. Other responses throughout the class period will be credited 1 point for each response. iClickers must be registered before class on Monday, August 31. iClicker technical assistance available from Cathy Webster (webster@unm.edu).How to get your 3 Digit ID and register with MP and iClicker
