The Tyndall Effect is the effect of light scattering in colloidal dispersion, while showing no light in a true solution. This effect is used to determine whether a mixture is a true solution or a colloid.
Just so, what is Tyndall effect explain it with an example?
Originally Answered: What is an example of the Tyndall effect? I had not heard of it,-but googling reveals: “The Tyndall effect is the scattering of light as a light beam passes through a colloid. The individual suspension particles scatter and reflect light, making the beam visible.

The Tyndall effect, also known as Willis–Tyndall scattering, is light scattering by particles in a colloids or in a very fine suspension. It is named after the 19th-century physicist John Tyndall.
An example of a colloid is milk. Milk is a mixture of liquid butterfat globules dispersed and suspended in water. Colloids are generally considered heterogeneous mixtures, but have some qualities of homogeneous mixtures as well. Smoke is a mixture of particles that are suspended in the air.
One type of colloid often encountered in cooking are hydrocolloids. These are gels (solid) or sols (liquid) made of particles dispersed in water. Gelatin is a sol when hot, and a gel when cooled. Other examples are jellies made from pectin, agar, carrageenan, or other gelling agents.
Definition: A colloid is a substance microscopically dispersed evenly throughout another substance. The dispersed-phase particles have a diameter between about 5 and 200 nanometers. Examples: Milk is an emulsion, which is a colloid in which both parties are liquids.
Colloidal solutions (also called colloidal suspensions) contain little particles, ranging from one to 1,000 nanometers in diameter. (A nanometer is very small—a human hair is about 100,000 nanometers wide!) For example, think of how sugar dissolves in water, making a homogenous solution.
Shaving cream is a special type of mixture called a colloid, consisting of tiny air bubbles dispersed in liquid. This particular type of colloid can further classified as a foam.
Ice cream is a colloid, a type of emulsion. An emulsion is a combination of two substances that don't normally mix together. Instead, one of the substances is dispersed throughout the other. In ice cream, molecules of fat are suspended in a water-sugar-ice structure along with air bubbles.
In mayonnaise, the emulsifier is egg yolk, which contains lecithin, a fat emulsifier. Chemically, emulsions are colloids, heterogeneous mixtures composed of tiny particles suspended in another immiscible (unmixable) material. The particles in a colloid can be solid, liquid or bubbles of gas.
Making ice cream is a change of state from a liquid (liquid mixture of cream and sugar) to a solid (ice cream) due to cooling from the ice and salt. Salt actually lowers the freezing point of water. Salt is used on icy roads in the winter to actually melt the ice. Water normally freezes at 0 degrees Celsius.
Sand is a solid because each grain of sand is just a very small solid that can hold its shape. When it is poured, the small grains of sand pile up on each other to form a small hill and not a flat surface. Furthermore, it does not completely fill the container like a liquid.
Ice cream (derived from earlier iced cream or cream ice) is a sweetened frozen food typically eaten as a snack or dessert. It is usually made from dairy products, such as milk and cream, and often combined with fruits or other ingredients and flavors.
Can an Ice Cream Diet Be Good for You? According to the newest diet featured in Prevention magazine, you can lose weight and eat ice cream once a day, too. The trick is moderation, and eating healthy meals the rest of the day. While on the diet, women may have 1 cup of ice cream, and men may have 1½ cups per day.
A typical air pocket in ice cream will be about one-tenth of a millimeter across. The presence of air means that ice cream is also a foam. Some of the most common ingredients in ice cream include ice crystals, air, fat globules, sugar (sucrose), and flavoring agents (such as vanillin).
Ice cream is also high in sugar, which makes up the majority of its carbohydrate content. The Mayo Clinic website warns that consumption of too much sugar may contribute to health problems such as weight gain, cavities and increased levels of blood triglycerides, another unhealthy type of fat.
Ingredients and Recipes Used for Homemade Ice Cream. The main constituents of ice cream are fat, milk solids-not-fat (skim-milk powder), sugar, gelatin (or other suitable stabilizer), egg and flavouring.
Eggs, specifically egg yolks, play several roles in homemade ice cream. You can make tasty ice cream without them, but there's a reason that almost every recipe published in the last 50 years calls for them. Here's why: After water, egg yolks are mostly fat and protein.
In its most basic form, ice cream is a mixture of cream and/or milk, sugar and sometimes eggs that is frozen while being churned to create a frozen product. In commercial ice-cream making, stabilizers, such as plant gums, are usually added and the mixture is pasteurized and homogenized.
Dry ice is made from carbon dioxide gas. The carbon dioxide gas is pressurized and cooled to form liquid CO2.
Cream is a dairy product composed of the higher-butterfat layer skimmed from the top of milk before homogenization. In un-homogenized milk, the fat, which is less dense, will eventually rise to the top. In the industrial production of cream, this process is accelerated by using centrifuges called "separators".
Cream cheese is a soft, mild-tasting fresh cheese made from milk and cream. Stabilizers such as carob bean gum and carrageenan are typically added in industrial production.
Your recipe calls for heavy cream and you're not sure—is that the same as whipping cream? 10% cream is often called half-and-half and sometimes called cereal cream. 18% cream can be called table cream or coffee cream. 33-36% cream is whipping cream. Heavy cream has at least 36% milk fat.
