Photosynthesis Wavelengths Of Light
PHOTOSYNTHESIS INFORMATION: The Nature of Light
Light behaves both as a wave phenomenon and as
discrete particles of energy called photons. If we
look at light as a wave phenomenon, we can assign
it a wavelength (the distance from one peak of the
wave to the next) and an amplitude (the distance
the wave oscillates from its centerline).
Different wavelengths of light have different
characteristic energies and properties. Light can
also travel at various speeds in different media,
producing a freq...
Half Life Process Nucleus Energy
The "big bang" which created the universe, only
created the elements Hydrogen (H) and Helium (He)
and possibly a very small amount of Lithium (Li).
However, a glance at the periodic table of the
elements shows that today (some 15 billion years
after the big bang) there are at least 108 known
elements. Every atom of every element heavier than
Li has been produced since the big bang! The
"factories" which make these elements are stars.
"Nucleosynthesis" or the synthesis of nuclei, is
the process b...
Excited State Atoms Energy Laser
The Laser/Atom Connection A laser is a device that
controls the way that energized atoms release
photons. Laser is an acronym for Light
Amplification by Stimulated Emission of Radiation,
which describes very succinctly how a laser works!
Although there are many types of lasers, all have
certain essential features. In a laser, the lasing
medium is "pumped" to get the atoms into an
excited state. Typically, very intense flashes of
light or electrical discharges pump the lasing
medium and create a ...
Robert Schumann Grillen From Fantasiestucke Opus 12
Music in the nineteenth century saw the creation
and evolution of new music genres such as the
piano miniature, short expressive piano pieces.

music during his time period. Schumann's uses
various qualities in his music such as form,
pitch, rhythm and meter, and text...

from the Sun Identifying Photosynthetic Reactants
And Products A. The water for photosynthesis in
land plants comes primarily from the soil and must
travel from the roots to leaves. B. Carbon dioxide
is taken in, and water and O 2 are released,
through tiny openings in leaves, called stroma ta.
C. Light is absolutely necessary for the
production of oxygen and carbohydrate. The
photosynthetic production of oxygen by green
plants is an important s...
