Question

Look the sky will be black in the day also in space! ​

Answer 1

Answer:

It's because our atmosphere. Blue light on the visible spectrum bounces more in our atmosphere, that's why sky appearsto be blue whereas in space, there's no medium for light to get scattered or reflected and thus it appears to be black

Answer 2

Explanation:

• So, when the Sun is high in the sky, blue light is scattered in all directions as sunlight passes through the atmosphere and we see the sky as blue.

• But during sunrise or sunset it's a different case. When the Sun is close to the horizon at sunset or sunrise the practical distance between us and the sun is more. Blue light as it scatters more is lost in the atmosphere.

• And having a short wavelength it doesn't reach the observer. Red light on the other hand has longest wavelength in the visible spectrum. Hence, we see the scattered red sky during sunrise or sunset.

For an astronaut, there's no atmosphere in space to scatter light. Hence, he see's the black space.
