3.2 Waves in What?
Terms in this set (9)
An elementary particle with a negative electric charge; one of the components of the atom.
An elementary particle carrying a positive electric charge, a component of all atomic nuclei. The number of protons in the nucleus of an atom dictates what type of atom it is.
A force that one charge exerts on another. When the charges are the same sign, they repel; when the charges are opposite, they attract.
A field extending outward in all directions from a charged particle, such as a proton or an electron. The electric field determines the electric force exerted by the particle on all other charged particles in the universe; the strength of the electric field decreases with increasing distance from the charge according to an inverse-square law.
Field that accompanies any changing electric field and governs the influence of magnetized objects on one another.
The union of electricity and magnetism, which do not exist as independent quantities but are in reality two aspects of a single physical phenomenon.
Oscillating electric and
magnetic fields. Changing electric field creates
magnetic field, and vice versa.
