Introduction to Photons
The way we
are able to perceive light is due to the photons that are flying through the
air. They originate from the light sources that are very likely to be around
you right now and then are reflected off the objects in the room. There are
usually billions or more photons zipping through the air at any given time, and
they are running on different frequencies depending on how they are created.
Speaking of that, how are photons made? They are all produced in the same way,
which involves the energizing of atoms.
Photon
Definition: A
photon is a discrete packet of energy associated with electromagnetic radiation
(light). A photon has energy E which is proportional to the frequency ν of the
radiation: E = hν, where h is Planck's constant.
Electrons do
not remain in an unnatural orbit for long, though, because they prefer to be in
their own orbit. In order to get back they produce a packet of energy, which is
a photon. Depending on the amount of energy released, the photon will be of
different frequencies and therefore colors. Sodium atoms, for example, give
off yellow photons and therefore yellow lights. Energizing atoms in a ruby
crystal, however, creates a red light of a different frequency. The sun is the
largest producer of photons in our solar system
Properties of
a Photon
Photons have some basic properties that help define what they are and how they behave. These properties include:
- They have zero mass.
- They have no electric charge.
- They are stable.
- They carry energy and momentum which are dependent on the frequency.
- They can have interactions with other particles such as electrons.
- They can be destroyed or created by many natural processes.
- When in empty space, they travel at the speed of light.
Photons Interact with Matter
Photons behave like particles in that they can interact with matter. In some cases the energy of the photon is absorbed by the matter. In this case the extra energy may be emitted as heat. One example of this is the blacktop of the road getting hot in the sun or a metal rod in fire.
Our eyes also interact with photons. When a photon strikes the eye it is turned
into electrical energy that is then transmitted to brain to form an image.
When the energy from photons is absorbed by matter, the matter can emit
electrons. This process is called the photoelectric effect. The photoelectric
effect is a property of light that is not explained by the theory that light is
a wave. This is one of the main reasons that scientists chose to treat light as
both a wave and a stream of particles.
Religious interpretation of a Photon
By lighting a lamp,
the lamp becomes a form of fire or “Tej” in Sanskrit. The lamp burns not to be
the light itself, but merely as a to create a message, to remind all who are present of
peace, positive brightness and that there is a existence of higher forces . Lighting a Deya before a ceremony
spreads divine grace.
One can regard the Photons as messengers of our creator. These messengers can take or bring information to
and from our creator. In a
prayer ritual, fire or flames of a fire is used to create the photons or messengers so that one can open a communication network with God or our creator.
