Technology / Home Audio / Dipole: A speaker design that uses two sets of drivers to generate equal amounts of sound both forward and backward, or side to side, with the two sounds being 'out of phase.' Dipoles are often used as surround speakers, and are very effective at creating a diffuse soundfield when placed on the sides of the listening position. Some speakers offer both dipole and bipole modes.

Dipole-Dipole Interaction

Science / Chemistry / Dipole-Dipole Interaction: Electrostatic attraction between oppositely charged poles of two or more dipoles. MORE

Electric Dipole Moment

Science / Chemistry / Electric Dipole Moment: A measure of the degree of polarity of a polar molecule. Dipole moment is a vector with magnitude equal to charge separation times the distance between the centers of positive and negative charges. Ch MORE

Electric Dipole

Science / Chemistry / Electric Dipole: An object whose centers of positive and negative charge do not coincide. For example, a hydrogen chloride (hcl) molecule is an electric dipole because bonding electrons are on average closer to the ch MORE
