• Photosynthesis Wavelengths Of Light
    612 words
    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 ...

    Music in the nineteenth century saw the creation and evolution of new music genres such as the piano miniature, short expressive piano pieces. During this time raw emotion and expressionism prevailed as the focus of music during this described "Romantic" movement. Robert Schumann's "Grillen", from Fantasiestucke, Opus 12 was written in July 1837 contains several virtues of music during his time period. Schumann's uses various qualities in his music such as form, pitch, rhythm and meter, and text...

    By Gerard Chretien Biology Photosynthesis: Energy 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...
