If there is no Sun, the colour of the sky would be ________

Question

নিচের অপশন গুলা দেখুন

• Blue
• Orange
• Yellow
• Black

Answer 1

সঠিক উত্তর হচ্ছে: Black

ব্যাখ্যা:

The sky appears blue because the sunlight is scattered by the gas molecules in the atmosphere - a phenomenon known as Rayleigh scattering - named after the discoverer - a British physicist who also discovered Argon - Lord Rayleigh (1842-1919). So, if there was no atmosphere, the sky would appear black.
