Question

what is tydnal effect​

Answer 1

Answer:

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. ... As with Rayleigh scattering, blue light is scattered more strongly than red light by the Tyndall effect.

✒ What is the Tyndall Effect ?

• The Tyndall effect is the phenomenon in which the particles in a colloid scatter the beams of light that are directed at them.
• This effect is exhibited by all colloidal solutions and some very fine suspensions.
• Therefore, it can be used to verify if a given solution is a colloid.
• The intensity of scattered light depends on the density of the colloidal particles as well as the frequency of the incident light.
• When a beam of light passes through a colloid, the colloidal particles present in the solution do not allow the beam to completely pass through.
• The light collides with the colloidal particles and is scattered.

✒ Examples of the Tyndall Effect

1. Milk is a colloid that contains globules of fat and protein. When a beam of light is directed at a glass of milk, the light is scattered. This is a great example of the Tyndall effect.

2. When a torch is switched on in a foggy environment, the path of the light becomes visible. In this scenario, the water droplets in the fog are responsible for the light scattering.

3. Opalescent glass has a bluish appearance when viewed from the side. However, orange-colored light emerges when light is shined through the glass.
