When a beam of light is passed through a colloidal solution, the light gets scattered. This phenomenon is known as the Tyndall effect.
The Tyndall effect occurs because colloidal particles are much larger than molecules of true solutions, and they scatter light in all directions. This scattering is more intense at shorter wavelengths of light (blue and violet), which is why the scattered light appears bluish to the observer.
Key points about the Tyndall effect:
– It is a phenomenon where light is scattered by colloidal particles or suspended particles in a medium.
– The scattered light is visible when the beam of light passes through the colloidal solution, making the path of the beam visible.
– This effect is used to distinguish between true solutions (where the particles are very small and do not scatter light) and colloidal solutions (where the particles are larger and scatter light).
In summary, when light is passed through a colloidal solution, it undergoes scattering due to the presence of larger particles in the solution, which is known as the Tyndall effect.
