tyndall effect การใช้

• 19th century physicist, John Tyndall, discovered the Tyndall effect.
• :Ordinarily, milk is coloured white because of the Tyndall effect.
• Sols are quite stable and show the Tyndall effect.
• :Does this refer to the Tyndall effect?
• Under the Tyndall effect, the longer-wavelength light is more reflected via scattering.
• However, macroscopically the affected tissues appear bluish grey because of a light-scattering phenomenon known as the Tyndall effect.
• But when smoke is present, the smoke particles and the Tyndall effect cause some of the light to be scattered back towards the detector.
• SFM can support a wide range of cinematographic effects and techniques such as motion blur, Tyndall effects, Dynamic Lighting, and depth of field.
• Some early morning and evening light ( golden hours ) has a lower color temperature due to increased low-wavelength light scattering by the Tyndall effect.
• :: Small smoke particles appear bluish-colored, but only if the particles are smaller than wavelengths of visible light, see Rayleigh scattering and Tyndall effect.
• A white powdered substance would be due to, what I assume, is the Tyndall effect, so has to do with the particle size, and not the identity of the substance.
• It is particularly applicable to colloidal mixtures and fine suspensions; for example, the Tyndall effect is used in nephelometers to determine the size and density of particles in aerosols and other colloidal matter ( see ultramicroscope and turbidimeter ).
• The brightness of the colours is neither the product of iridescence ( except in the American kingfishers ) or pigments, but is instead caused by the structure of the feathers, which causes scattering of blue light ( the Tyndall effect ).
• In a statistical sense, elastic scattering of light by numerous particles much smaller than the wavelength of the light is a process known as Rayleigh scattering while the similar process for scattering by particles that are similar or larger in wavelength is known as Mie scattering with the Tyndall effect being a commonly observed result.
• If the microstructures are spaced randomly, light of shorter wavelengths will be scattered preferentially to produce Tyndall effect colors : the blue of the sky ( Rayleigh scattering, caused by structures much smaller than the wavelength of light, in this case air molecules ), the luster of opals, and the blue of human irises.
• The Tyndall effect is seen when light-scattering particulate-matter is dispersed in an otherwise-light-transmitting medium, when the cross-section of an individual particulate is the range of roughly between 40 and 900 nanometers, i . e ., somewhat below or near the wavelength of visible light ( 400 750 nanometers ).
• While it shows up in the bottle, the amount of dye in one use of the gel is likely not enough to change the colour of the large quantity of bathwater, which I think gets its greenish-blue colour due to the Tyndall effect or Rayleigh scattering .-talk ) 15 : 50, 19 November 2008 ( UTC)
