Although modern quantum optics tells us that there also is a semi-classical explanation of the photoelectric effect —the emission of electrons from metallic surfaces subjected to electromagnetic radiation —the photon was historically although not strictly necessarily used to explain certain observations. It is found that increasing the intensity of the incident radiation so long as one remains in the linear regime increases only the number of electrons ejected, and has almost no effect on the energy distribution of their ejection. Only the frequency of the radiation is relevant to the energy of the ejected electrons. This quantum picture of the electromagnetic field which treats it as analogous to harmonic oscillators has proven very successful, giving rise to quantum electrodynamics , a quantum field theory describing the interaction of electromagnetic radiation with charged matter. It also gives rise to quantum optics , which is different from quantum electrodynamics in that the matter itself is modelled using quantum mechanics rather than quantum field theory.
David Jeffrey Griffiths born is a U.
He worked at Reed College from through , becoming the Howard Vollum Professor of Science before his retirement. He is not to be confused with the late physicist David J.
He is principally known as the author of three highly regarded textbooks for undergraduate physics students: Introduction to Elementary Particles published in , second edition published , Introduction to Quantum Mechanics published in , third edition published , and Introduction to Electrodynamics published in , fourth edition published in He was also the recipient of the Robert A.
Millikan award reserved for "those who have made outstanding scholarly contributions to physics education".
The most recent edition of each book is generally regarded as a standard undergraduate text. From Wikipedia, the free encyclopedia. For other people named David Griffiths, see David Griffiths disambiguation. Jan Oregon State U. Physics Newsletter.

An electric field is produced when the charge is stationary with respect to an observer measuring the properties of the charge, and a magnetic field as well as an electric field is produced when the charge moves, creating an electric current with respect to this observer. Over time, it was realized that the electric and magnetic fields are better thought of as two parts of a greater whole — the electromagnetic field.
Until , when the Danish physicist H. In , Michael Faraday made the seminal observation that time-varying magnetic fields could induce electric currents and then, in , James Clerk Maxwell published his famous paper A Dynamical Theory of the Electromagnetic Field.
If these other charges and currents are comparable in size to the sources producing the above electromagnetic field, then a new net electromagnetic field will be produced.
Thus, the electromagnetic field may be viewed as a dynamic entity that causes other charges and currents to move, and which is also affected by them. These interactions are described by Maxwell's equations and the Lorentz force law. This discussion ignores the radiation reaction force. Feedback loop[ edit ] The behavior of the electromagnetic field can be divided into four different parts of a loop:  the electric and magnetic fields are generated by moving electric charges, the electric and magnetic fields interact with each other, the electric and magnetic fields produce forces on electric charges, the electric charges move in space.
A common misunderstanding is that a the quanta of the fields act in the same manner as b the charged particles, such as electrons, that generate the fields. The speed ratio between charged particles in a conductor and field quanta is on the order of one to a million.
Maxwell's equations relate a the presence and movement of charged particles with b the generation of fields. Those fields can then affect the force on, and can then move other slowly moving charged particles. Charged particles can move at relativistic speeds nearing field propagation speeds, but, as Einstein showed[ citation needed ], this requires enormous field energies, which are not present in our everyday experiences with electricity, magnetism, matter, and time and space.
