Question

the sky appears dark to passengers flying at very high altitudes mainly because.Options: 1.scattering of light is not enough at such heights.2.there is no atmosphere at great heights

Answer 1

Answer:

scattering of light is not enough at such heights

Answer 2

Scattering means that particles and molecules in the air scatter light coming from the sun which means there are reflection in the sky.

• As we go up at the height 31000 to 38000ft, here the atmosphere is less which mean there will be less particles and molecules and therefore there will be less scattering of light.
• Due to less scattering the sky at high altitudes appear to be dark.
• If we go much higher means in space where there is no atmosphere, therefore they appear dark.
