Stimulated emission is a fundamental process in quantum mechanics and is key to the operation of lasers (Light Amplification by Stimulated Emission of Radiation). It occurs when an excited atom or molecule, which has absorbed energy and is in an excited state, is induced to emit a photon (a particle of light) of a specific wavelength.
Transverse mode by Wikipedia Bot 0
Transverse mode is a term commonly used in the context of wave phenomena, particularly in optics and photonics, as well as in the description of electromagnetic waves. It generally refers to a mode of propagation where the oscillations or variations occur perpendicular (transverse) to the direction of wave propagation.
Triboluminescence by Wikipedia Bot 0
Triboluminescence is a phenomenon in which light is emitted when certain materials are mechanically stressed, such as by scratching, crushing, or rubbing. This process occurs due to the generation of electrical charges that result from the breaking of chemical bonds in the material, which then recombine and release energy in the form of light.
Lighting by Wikipedia Bot 0
Lighting refers to the use of light to achieve practical or aesthetic effects in various environments. It plays a critical role in illuminating spaces, enhancing visibility, and influencing mood and atmosphere. There are different types of lighting, including: 1. **Natural Lighting**: Light that comes from natural sources, primarily the sun. This can include direct sunlight or indirect light that is reflected off surfaces.
Vision by Wikipedia Bot 0
Vision can refer to different concepts depending on the context: 1. **Biological Vision**: In a biological sense, vision refers to the ability of organisms to perceive their environment through light. It involves the process of capturing light through the eyes, which is then processed by the brain to create an image of the surrounding world. This capability allows individuals to navigate their environment, recognize objects, and understand spatial relationships.
Ballistic photon by Wikipedia Bot 0
The term "ballistic photon" typically refers to photons that travel through a medium without being scattered or absorbed significantly. This means that these photons maintain a straight path over considerable distances, unlike most photons which may undergo scattering events as they interact with particles in a medium. In the context of physics and optical studies, ballistic photons are discussed in relation to phenomena such as quantum optics and imaging.
Diffuse sky radiation refers to the portion of solar radiation that is scattered by molecules and particles in the atmosphere and arrives at the Earth's surface from all directions in the sky, rather than directly from the sun. This type of radiation can be influenced by various factors, including atmospheric conditions, cloud cover, and the presence of aerosols. Diffuse sky radiation is significant in various fields, including meteorology, climatology, and solar energy.
Luminous flame by Wikipedia Bot 0
The term "luminous flame" generally refers to a flame that emits visible light, often characterized by its brightness and the colors it might produce. Luminous flames are typically associated with combustion processes where certain temperatures and conditions produce incandescence. In a scientific context, a luminous flame can occur during the burning of hydrocarbons, such as those found in candles or gas stoves.
Phototropism by Wikipedia Bot 0
Phototropism is the growth response of plants to light direction. It is a form of directional growth where plant parts, such as stems and leaves, grow towards a light source. This phenomenon is primarily driven by the plant hormone auxin, which regulates cell elongation. When light is more intense on one side of the plant, auxin accumulates on the shaded side, promoting cell elongation on that side. Consequently, the plant bends toward the light to maximize light absorption for photosynthesis.
Spectrum by Wikipedia Bot 0
The term "spectrum" can refer to various concepts depending on the context in which it is used. Here are some common interpretations: 1. **Physics and Light**: In physics, a spectrum refers to the range of different wavelengths of electromagnetic radiation. This includes visible light, which can be split into a spectrum of colors (red, orange, yellow, green, blue, indigo, violet) through a prism.
Visual MIMO by Wikipedia Bot 0
Visual MIMO (Multiple Input Multiple Output) is a technology that extends the principles of traditional MIMO systems, which are commonly used in wireless communications, to the realm of visual data transmission and processing. While traditional MIMO leverages multiple antennas to transmit and receive radio signals, Visual MIMO involves the use of multiple cameras or visual sensors to capture, process, and transmit visual information.

Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
We have two killer features:
  1. topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculus
    Articles of different users are sorted by upvote within each article page. This feature is a bit like:
    • a Wikipedia where each user can have their own version of each article
    • a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
    This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.
