Question

Give an example of a phenomena where Tyndall effect can be observed: A. red colour of sky B. rainbow formation in the sky C. twinkling of stars D. none of these​

Answer 1

Answer:

D. none of these​

Answer 2

Tyndall effect can be observed in None of the options. (Option D)

• The crimson hue of the sky is caused by light scattering. The rising sun appears red because the sun is close to the horizon, requiring the sunlight to travel a greater distance through the atmosphere, scattering away from the blue light by air particles.
• A rainbow is generated as a result of the dispersion and entire internal reflection of sunlight by microscopic water droplets in the sky.
• The star's sparkling is caused by atmospheric refraction.

The Tyndall effect is the light scattering by colloidal particles. The scattering of the light beam, when passed through a glass of milk, is an example of the Tyndall effect.
