Question

why is the colur of sky blue​

Answer 1

Answer:

1. The sky is also called the celestial sphere.

2. This is an abstract sphere, concentric to the Earth, on which the Sun, Moon, planets, and stars appear to be drifting.

3. The blue color of the sky is due to the scattering of light by small particles of the atmosphere (air molecules) when the light is incident on particles whose size is smaller than the wavelength of light, it is scattered.

4. When sunlight passes through the atmosphere, the fine particles in the air scatter the blue color (shorter wavelengths) more strongly than red.

5. The scattered blue light enters our eyes.

6. Within the visible range of light, red light waves are scattered the least by atmospheric gas molecules.
