Electromagnetic radiation is produced whenever a charged particle, such as an electron, changes its velocity —i.e., whenever it is accelerated or decelerated. The energy of the electromagnetic radiation thus produced comes from the charged particle and is therefore lost by it.
Read moreDoes electromagnetic have frequency?
Electromagnetic radiation can be expressed in terms of energy, wavelength, or frequency . Frequency is measured in cycles per second, or Hertz. Wavelength is measured in meters.
Read moreWhat is electromagnetic frequency?
Frequency is the number of cycles of a wave to pass some point in a second . The units of frequency are thus cycles per second, or Hertz (Hz). Radio stations have frequencies. They are usually equal to the station number times 1,000,000 Hz.
Read moreWhat is an electromagnetic?
An electromagnet is a type of magnet in which the magnetic field is produced by an electric current . Electromagnets usually consist of wire wound into a coil. A current through the wire creates a magnetic field which is concentrated in the hole, denoting the center of the coil.
