The Tyndall effect was first discovered by (and is named after) the Irish physicist John Tyndall. The diameters of the particles that cause the Tyndall effect can range from 40 to 900 nanometers (1 nanometer = 10-9 meter). In comparison, the wavelength of the visible light spectrum ranges from 400 to 750 nanometers. Examples of the Tyndall Effect

Tyndall effect: “The phenomenon of scattering of a beam of light by colloidal particles, when passed through a colloidal solution, is called the Tyndall effect”. When light is passed through a colloidal solution, it is observed that the colloidal particles do …

Faraday first observed this effect and was further studied by Tyndall that’s why it is called the Tyndall effect. Tyndall cone can also be observed which is the bright cone of light. The path of the beam is illuminated by the scattering of light in the colloidal dispersion. If these two conditions are satisfied then we can observe Tyndall effect:

2012年10月14日 · The Tyndall effect is a bluish discoloration that appears if hyaluronic acid fillers are injected too superficially into the skin. The filler is a clear gel so when light reflects through it through the skin it appears bluish. It is possible that what you are seeing is the Tyndall effect.

The phenomenon by which colloidal particles scatter light is called Tyndall effect. The particles of colloids scatter a beam of light passing through it and make its path visible. True solutions do not show Tyndall effect. Scattering of light or Tyndall Effect …

Tyndall effect: The phenomenon in which the solute particles of a colloid scatter the beam of light and show its path is called the Tyndall effect. The colloidal solution has the property of the Tyndall effect. For example, a starch solution which is also a …

2023年11月21日 · The Tyndall effect is how the light scatters against those particles, allowing a beam of light to be seen within the colloid itself. Video Transcript What is a Colloid? Colloids are important in ...

The first picture looks like a bruise (was this taken earlier?). After 5 weeks one would not expect to still see a bruise. Judging from the second and third photos I vote for Tyndall effect (which is actually a bluish color under the skin due to light reflecting over the filler).

2010年4月8日 · The Tyndall effect refers to a bluish color from small particles reflecting light in a transparent medium. Sometimes the hyaluronic acid fillers when injected into a superficial position can cause this bluish color. It will last for the duration of the filler's presence, although it may lighten as the particles of the filler lessen.

2018年12月15日 · Thank you for your question! There are two main causes for the blueish effect that you see in this photo. The first in an actual Tyndall effect, which is the way light reflects through a clear filler under the skin. The second cause is blood trapped or swirled throughout the filler that is under the skin.
