Question

why sky is blue?
explain briefly ​

Answer 1

Answer:

Gases and particles in Earth's atmosphere scatter sunlight in all directions. Blue light is scattered more than other colors because it travels as shorter, smaller waves. This is why we see a blue sky most of the time.

Answer 2

Answer:

The sky is blue due to a phenomenon called Raleigh scattering. This scattering refers to the scattering of electro- magnetic radiation (of which light is a form) by particles of a much smaller wavelength. These shorter wavelengths correspond to blue hues, hence why when we look at the sky, we see it blue.
