Is tyndall effect exhibited by the dust particles suspended in the movie projector's beam of light in a dark room?
The Tyndall effect, also called Tyndall scattering, is light scattering via particles in a fine suspension. This effect normally creates strange color tinges when only this scattered light is seen, whereas with the movie projector the only real effect of the dust is revealing the beam of light, as the light itself still hits the screen clearly.

Is pure cow milk a pure substance or mixture?
Answer Yes, milk is regarded as a mixture and not a pure substance. To be more specific, milk is a colloidal mixture. In a colloidal mixture, particles are suspended freely in the solvent. In milk, the particles consist of fatty acids, proteins, mineral ions etc. in a solvent of water (constituting most of the solvent part). Colloidal mixtures exhibit a typical effect called the Tyndall Effect. You can demonstrate Tyndall Effect in your room itself. Take a jar containing a mixture of milk and water in an approximate ratio of 5:1. Place it in your room and darken the room by turning off all lights and putting the curtains. Apply a focus of torch light on the mouth of the jar. The shine produced as such is called the Tyndall Effect, which is exhibited only by colloidal mixtures like milk, BLOODY ETC. It is a mixture of many, many different substances. it is a mixture so,it is not a pure substance
A visible sunbeam is an example of?
Visible light is an example of electromagnetic radiation.NO it is electromagnetic energy.actually it electromagnetic waves =P
Why is cytoplasm a colloidal system?
Cytoplasm is a transluscent, viscous fluid It has many inorganic molecules like water, salts and various organic compounds like proteins, carbohydrates and lipids. There are also nucleoproteins, nucleic acids and several enzymes in it. The protein particles, carbohydrates and salts are hydrophilic while fat globules are hydrophobic.The viscosity of cytoplasm changes under the influence of tmperature. The suspended particles display Tyndall Effect.Cytoplasm also shows resistance to flow freely which keeps the particles/suspensions floating and not settling down due to gravitational pull.All these properties (common to colloids) prove the colloidal nature of the cytoplasm beyond doubt.
What are the differences between true and false solutions?
A true solution is homogeneous, that is the same all the way through, and you can't see the solute particles nor filter them out. A false solution is properly called a suspension or colloidal suspension. They are heterogeneous and you may or may not be able to see the solid pieces. Colloidal suspensions scatter light.

Will rubber show tyndall effect?
No, rubber does not show the Tyndall effect. The Tyndall effect is the scattering of light by colloidal particles or particles suspended in a transparent medium, which causes the light to be visible as a beam. Rubber does not have the scattering properties required to exhibit this effect.
Does human blood show tyndall effect?
Yes, human blood can exhibit the Tyndall effect when a light is shone through it. This is due to the presence of suspended particles like proteins and cells that scatter the light. It is commonly used in laboratories to detect and analyze these suspended particles in blood samples.
Why do colloids show the Tyndall effect?
In true solutions the solute dissolves completely in the solvent at the molecular level, meaning that the solute particles are present at their molecular size - well below the size of a particle required to exhibit light scattering dispersion (the Tyndall effect).
What mixtures scatter a beam of light that passes through them-a phenomenon called the Tyndall effect?
These mixtures are colloids or very fine suspensions.
The scattering of light by colloidal particles?
This is because there are solid particles suspended in the mixture although it is more stable than a suspension.
Who gave their name to the Tyndall effect?
The Tyndall effect, or Tyndall scattering, was named after 19th century physicist John Tyndall. It has to do with light scattering through particles in a suspension.
A solution shows a Tyndall effect or soap shows Tyndall effect?
The Tyndall effect is the phenomenon where light is scattered by particles in a colloidal solution or suspension, making the beam visible. If a solution is showing the Tyndall effect, it indicates the presence of suspended particles that are large enough to scatter light. In the case of soap, the Tyndall effect may be observed when light is scattered by micelles or other structures in the soap that are similar in size to the wavelength of visible light.
Why does smoke show tyndall effect?
The Tyndall effect occurs when light is scattered by particles in a colloid or very fine suspension. Smoke consists of tiny solid particles dispersed in air, which are large enough to scatter light but small enough to remain suspended. When a beam of light passes through smoke, these particles scatter the light, making the beam visible. This phenomenon highlights the presence of the small particles in the smoke.
The scattering of light by a colloid is called?
The scattering of light by a colloid is called Tyndall effect. This effect occurs when light is scattered by particles within a colloid, making the beam of light visible due to the reflection and absorption of light by the colloidal particles.
Does a sugar solution show the Tyndall effect?
No, a sugar solution does not typically show the Tyndall effect. The Tyndall effect is the scattering of light by colloidal particles, but sugar molecules are generally too small to scatter light effectively.
