Question

Why does the sky appear blue during the day?where should you place an object with respect to a convex lens if you intend to use the latter as a magnifying glass
​

Answer 1

Answer: Sunlight reaches Earth's atmosphere and is scattered in all directions by all the gases and particles in the air. Blue light is scattered more than the other colours because it travels as shorter, smaller waves.

Explanation:

When sunlight reaches the Earth, it scatters to different positions by all the gases and particles in the air. Blue light is more frequently seen because it travels as shorter and smaller waves

Hope this helps! :D

Answer 2

Answer:

It is basically because of the phenomenon of Scattering.Sunlight get scattered by small air molecules during its passage through the atmosphere .Also note that all the 7 colours of sunlight does not scatteres at the same rate .Scattering is inversely proportional to wavelength that is blue with the shortest wavelength will scatter more compared to red with the highest wavelength.In short, as a result of this greater scattering of blue light by the air molecules in all directions make the atmosphere appear blue during cloudless daytime.
