Question
Which of the following would not happen if there was no atmosphere around the Earth?
- The sky would be black.
- the stars would not twinkle.
- The sun would appear white always.
- The clouds would appear blue.
Hint:
No atmosphere would mean no particles to scatter light
The correct answer is: The clouds would appear blue.
Since there would be no refraction or scattering due to absence of any particles to refract or scatter light, no color would appear and hence the clouds too can't appear blue.
