why does sky looks blue?

Answers

Answered by shruti1618

A clear cloudless day-time sky is blue because molecules in the air scatter blue light from the sun more than they scatter red light. When we looktowards the sun at sunset, we see red and orangecolours because the blue light has been scattered out and away from the line of sight.

NiteshKushwaha1: how air scatters blue light

shruti1618: Sunlight reaches Earth's atmosphere and isscattered in all directions by all the gases and particles in the air. 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.

NiteshKushwaha1: travel shorter, smaller waves means

shruti1618: You know what wavelength means. It is the distance between two successive crests or troughs of the wave. Now, a wave which has a small wavelength has a high frequency and subsequently a high energy.
Now, when a wave has a small wavelength, even small objects scatter it. Just imagine it. If the wavelength is large, it will pass over or miss smaller particles in between its crests and troughs. This analogy should make it clearer.

shruti1618: Also, rayleigh scattering is inversely proportional to the wavelength. This means the phase change produced on scattering is high for those waves with small wavelengths.

shruti1618: Just go away from here

shruti1618: Idiot

NiteshKushwaha1: sorry

We know that there are seven colours coming from the sun.But the blue colour has more power than all other six colours that's why sky looks blue.
