Lasers
The laser is a device that a beam of light that is both scientifically
and practically of great use because it is coherent light. The beam is produced
by a process known as stimulated emission, and the word "laser" is an acronym
for the phrase "light amplification by stimulated emission of radiation."
Light is just like radio waves in the way that it can also carry
information. The information is encoded in the beam as variations in the
frequency or shape of the light wave. The good part is that since light waves
have much higher frequencies they can also hold much more information.
Not only is the particle the smallest light unit but it is a particle as
well as a wave. In beams of light whether they are ordinary natural or
artificial the photon waves will not be traveling together because they are not
being emitted at exactly the same moment but instead at random short bursts.
Even if the light is of a single frequency that statement would also be true. A
