Answer 2

Answer:

Q. Why sky appears blue?

=> the scattering of the blue component of white sunlight by air molecules present in the atmosphere causes the blue colour of the sky.

Q. Why stars appears to be twinkle?

=> The stars twinkle in the night sky because of the effects of our atmosphere. When starlight enters our atmosphere it is affected by winds in the atmosphere and by areas with different temperatures and densities. This causes the light from the star to twinkle when seen from the ground.

Q. Why the sun appears red at sunrise and sunset?

=> Because at that time most of the blue colour present in the sunlight has been scattered out leaving behind mainly red colour in the direct sunlight beam that reaches our eyes.
