Question

why is sky blue in colour​

Answer 1

Answer:

Hello mate...

Blue light is scattered in all directions by the tiny molecules of air in Earth's atmosphere. Blue 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. Closer to the horizon, the sky fades to a lighter blue or white.

the red light has more wavelength about 1.8 times greater than blue light .... when sunlight passes through atmosphere,the fine particles in air scatter the blue colour more bcoz of shorter wavelength ....
