Among the options given below, which of the following exhibit tyndall effect?
(i) Sunlight passing through clouds
(ii) Milk in a glass
(iii) Sunlight coming in through windows
Among the options given below, which of the following exhibit tyndall effect?
(i) Sunlight passing through clouds
(ii) Milk in a glass
(iii) Sunlight coming in through windows
The correct option is D (i), (ii) and (iii)
Tyndall effect is the phenomena by which the path of light becomes visible due to scattering of light by particles. All of the examples show Tyndall effect because:
1. The path of the sun rays coming in through clouds is visible because clouds are colloids and they scatter light and make its path visible.
2. When a beam of light is made to pass through milk in a glass, its path becomes visible as milk is a colloid and light passing through it gets scattered.
3. The path of sunlight when it comes in through windows becomes visible, especially if there are lots of dust particles. The suspended dust particles scatter the light and make its path visible.
