An introductory course intended primarily for nonscience majors. This interdisciplinary course focuses on the subject of LIfe in the Universe. We will study historical astronomy, gravitation and planetary orbits, the origin of the chemical elements, the discoveries of extrasolar planets, the origin of life on Earth, the evolution and exploration of the Solar Systen, global climate change on Venus, Mars and Earth, and the Search for Extraterrestrial Life (SETI).
You cannot receive credit for this course and for ASTR UN1403 or ASTR UN1453.
Can be paired with the optional Lab class ASTR UN1903.
Charge, electric field, and potential. Gausss law. Circuits: capacitors and resistors. Magnetism and electromagnetism. Induction and inductance. Alternating currents. Maxwells equations. This is a calculus-based class. Familiarity with derivatives and integrals is needed.
PLEASE NOTE: Students who take PHYS BC2002 may not get credit for PHYS BC2019 or PHYS BC2020.
PHYS BC2020 Electricity & Magnetism -- Lecture Only is required as a pre- or co-requisite for this lab.
Prerequisite: Physics BC2001 or the equivalent.
Charge, electric field, and potential. Gauss's law. Circuits: capacitors and resistors. Magnetism and electromagnetism. Induction and inductance. Alternating currents. Maxwell's equations. This is a calculus-based class. Familiarity with derivatives and integrals is needed.
Prerequisites: BC3001 or C2601 or the equivalent. Wave-particle duality and the Uncertainty Principle. The Schrodinger equation. Basic principles of the quantum theory. Energy levels in one-dimensional potential wells. The harmonic oscillator, photons, and phonons. Reflection and transmission by one-dimensional potential barriers. Applications to atomic, molecular, and nuclear physics.
Experiments illustrating phenomenological aspects of the early quantum theory: (i) Hydrogenic Spectra: Balmer Series - Bohr-Sommerfeld Model; (ii) Photoelectric Effect: Millikans Determination of h/e; (iii) Franck-Hertz Experiment; and (iv) Electron Diffraction Phenomena. Substantial preparation required, including written and oral presentations, as well as an interest in developing the knack and intuition of an experimental physicist. This course is best taken concurrently with PHYS BC3006 Quantum Physics.
Classical electromagnetic wave phenomena via Maxwells equations, including: (i) Michaelson and Fabry-Perot Interferometry, as well as a thin-film interference and elementary dispersion theory; (ii) Fraunhofer Diffraction (and a bit of Fresnel); (iii) Wireless Telegraphy I: AM Radio Receivers; and (iv) Wireless Telegraphy II: AM Transmitters. Last two labs pay homage to relevant scientific developments in the period 1875-1925, from the discovery of Hertzian waves to the Golden Age of Radio. Complements PHYS W3008 Electromagnetic Waves and Optics.
Prerequisites: Permission of the departmental representative required. For specially selected students, the opportunity to do a research problem in contemporary physics under the supervision of a faculty member. Each year several juniors are chosen in the spring to carry out such a project beginning in the autumn term. A detailed report on the research is presented by the student when the project is complete.
