... In an experiment with a vacuum photocell to verify the Einstein’s equation for emission of photoelectrons from a metal surface, the maximum kinetic energy of the emitted photoelectrons was determined for different wavelength of the incident radiation. The following results were obtained: Wavelength ...

The Lorentz Oscillator and its Applications
... In equilibrium, the electric fields of the electrons and the ionized nuclei cancel each other out, but this equilibrium is hardly maintained. Instead of dealing with the individual (chaotic!) motion of electrons and nuclei, consider the center of mass of the nuclei and the center of mass of the elec ...

CHAPTER 28 Sources Of Magnetic Field
... Waves emitted by a radio transmitter are usually linearly polarized. Light from ordinary sources, such as light bulbs, is not polarized. Such light is called unpolarized light or natural light. To create a polarized light from unpolarized natural light requires a filter. The most common polarizing f ...

Time in physics

Time in physics is defined by its measurement: time is what a clock reads. In classical, non-relativistic physics it is a scalar quantity and, like length, mass, and charge, is usually described as a fundamental quantity. Time can be combined mathematically with other physical quantities to derive other concepts such as motion, kinetic energy and time-dependent fields. Timekeeping is a complex of technological and scientific issues, and part of the foundation of recordkeeping.
