(A) light is least scattered
(B) all the colours of the white light are scattered away
(C) blue colour is scattered the most
(D) red colour is scattered the most
Answers
At noon, the sun appears white as light is least scattered.
Explanation for correct option:
1. So, the correct choice of the asked question is Option (A).
2. We know that scattering of light occurs due to the presence of dust of other particles that remains suspended in the air.
3. During noon time, the sun is present overhead. And when sun is overhead, scattering is reduced as light from sun has to travel less distance through air.
4. And since the light from the sun has to travel small distance, so scattering is also reduced and hence during noon time, the sun appears white in colour.
5. During this time, only small part of blue and violet colors are scattered and hence the sun appears white.
Explanation for incorrect options:
• Option (C) is incorrect because when blue colour is scattered most, the sky looks blue.
• Option (D) is incorrect because the sky would look red if red color is scattered most.
• Option B, C and D are incorrect choices.
