Physics 10 – Lecture 18: Quantum II
 |
Physics 10: Physics for Future Presidents. Spring 2006. Professor Richard A. Muller. The most interesting and important topics in physics, stressing conceptual understanding rather than math, with applications to current events. Topics covered may vary and may include energy and conservation, radioactivity, nuclear physics, the Theory of Relativity, lasers, explosions, earthquakes, superconductors, and quantum physics.

Quantum Mechanics The Uncertainty Principle Light Particle’s
 |
www.myspace.com Single photons are the smallest quantities of light and, despite having no mass, have many properties in common with particles. In fact, physicists often think of photons as particles — particles that sometimes behave like waves. Physicists sometimes describe all particles as waves — even those with mass, such as electrons and protons — in order to better understand certain aspects of their behavior.

Quantum Mechanics
 |
www.myspace.com The Danish physicist Niels Bohr, who worked in Rutherford's lab, was the first to describe orbits of fixed size and energy in which electrons are free to travel without losing energy and falling toward the nucleus. According to this model, published in 1913, electrons can only occupy or jump between fixed energy levels and cannot reside in between these levels. In addition, once in their "ground state," electrons maintain the energy they contain. This energy keeps them in perpetual motion, allowing them to resist the attractive force of the nucleus.
