Electromagnetic radiation is produced every time a charged particle, akin to an
electron, modifications its velocity-i.e., whenever it's accelerated or
decelerated. The power of the electromagnetic radiation thus produced comes from
the charged particle and is therefore lost by it. A standard example of this
phenomenon is the oscillating charge or current in a radio antenna. The antenna
of a radio transmitter is a part of an electrical resonance circuit in which the
cost is made to oscillate at a desired frequency. An electromagnetic wave so
generated can be acquired by a similar antenna linked to an oscillating electric
circuit within the tuner that's tuned to that same frequency. The
electromagnetic wave in turn produces an oscillating motion of cost within the
receiving antenna. On the whole, one can say that any system which emits
electromagnetic radiation of a given frequency can soak up radiation of the same
frequency.
Such man-made transmitters and receivers develop into smaller with lowering
wavelength of the electromagnetic wave and prove impractical within the
millimeter range. At even shorter wavelengths right down to the wavelengths of X
rays, which are a million instances smaller, the oscillating prices arise from
transferring prices in molecules and atoms.
One may classify the era of electromagnetic radiation into two classes:
(1) programs or processes that produce radiation overlaying a broad continuous
spectrum of frequencies and
(2) people who emit (and soak up) radiation of discrete frequencies which can be
attribute of explicit systems. The Solar with its steady spectrum is an example
of the primary, while a radio transmitter tuned to 1 frequency exemplifies the
second category.
