lines of force
Physics; Electromagnetism
Lines that show how the force of an electric or magnetic field is working. Magnetic lines of force attract iron.
microwave
Physics; Electromagnetism
A wave of electromagnetic radiation that has wave-lengths that are shorter than radio waves but longer than infrared light.
Oersted
Physics; Electromagnetism
Danish scientist who founded the scientific study of electromagnetism in 1819. He proved that electric current produces magnetic force.
phosphorescent
Physics; Electromagnetism
Giving off light as a result of having been struck by electromagnetic radiation, such as visible light or x-rays.
photon
Physics; Electromagnetism
The particle of energy that makes up light and other forms of electromagnetic radiation. A beam of light is a stream of photons.
polarized light
Physics; Electromagnetism
Light that is made up of electromagnetic waves that vibrate in only one direction, instead of many.
quantum
Physics; Electromagnetism
A unit that is used to measure energy, especially in the form of electromagnetic radiation.
