(physics) the conversion of electromagnetic radiation into electric power through absorption by a semiconducting material

(physics, fluid mechanics) The reduction in fluid pressure that results when a fluid flows through a constriction.

(chemistry) the mesomeric effect

(film, television) An effect that cannot be reasonably achieved by normal means, as for example by the digital manipulation of previously filmed footage.

(physics) Birefringence of a material induced by an electric field due to partial orientation of its molecules.

(physics) the reversible change in temperature that accompanies the change of magnetization of a ferromagnetic or paramagnetic material

(physics) the resonant and recoil-free emission and absorption of gamma rays by atoms in the solid state; the basis of a type of spectroscopy with applications in both physics and chemistry

To alter as a side effect.

(physics) The total expulsion of magnetic flux from the interior of a superconducting metal when it is cooled in a magnetic field below a critical temperature, near absolute zero, at which the transition to superconductivity takes place.

(physics) the effect in which a conductor that carries an electric current perpendicular to an applied magnetic field develops a voltage gradient transverse to both current and field
