61Piezoelectricity — is the ability of some materials (notably crystals and certain ceramics, including bone) to generate an electric potentialPrinciples of Instrumental Analysis. 6th Edition, 2007. Skoog, Holler, and Crouch. Chapter 1, Sec. 1C 4, Pg. 9.] in response …
62Free electron model — In three dimensions, the density of states of a gas of fermions is proportional to the square root of the kinetic energy of the particles. In solid state physics, the free electron model is a simple model for the behaviour of valence electrons in …

64Vibration — For the soul music group, see The Vibrations. For the machining context, see Machining vibrations. For the albums, see Vibrations (Roy Ayers album) and Vibrations (The Three Sounds album). Classical mechanics …
65Transition dipole moment — The Transition dipole moment or Transition moment, usually denoted scriptstyle{mathbf{d} {nm for a transition between an initial state, scriptstyle{m}, and a final state, scriptstyle{n}, is the electric dipole moment associated with the… …
66Dielectric — A dielectric is an electrical insulator that can be polarized by an applied electric field. When a dielectric is placed in an electric field, electric charges do not flow through the material, as in a conductor, but only slightly shift from their …
67Crystal optics — is the branch of optics that describes the behaviour of light in anisotropic media, that is, media (such as crystals) in which light behaves differently depending on which direction the light is propagating. The index of refraction depends on… …
68SI derived unit — The International System of Units (SI) specifies a set of seven base units from which all other units of measurement are formed, by products of the powers of base units. These other units are called SI derived units, for example, the SI derived… …
69Poisson's equation — In mathematics, Poisson s equation is a partial differential equation with broad utility in electrostatics, mechanical engineering and theoretical physics. It is named after the French mathematician, geometer and physicist Siméon Denis Poisson.… …
