प्रश्न
In an experiment to study the scattering of light by passing a beam of white light through a colloidal solution of sulphur in a transparent glass tank:
Which colour is observed from the sides of the glass tank? Does this colour correspond to the colour of sky on a clear day or the colour of sky around the sun at sunset?
उत्तर
Blue colour is observed from the sides of the glass tank. The colour blue corresponds to the colour of the sky on a clear day. This is because blue light is scattered easily by the gas molecules of the air in the atmosphere. This scattered light reaches our eyes, which makes the sky appear blue.
