have you ever wondered why the sky is blue ? what cause it ? how it happens? maybe not now
you know a lot of are grown up now and we tend to worry about other things about life
maybe some curious kids wonder about the same.
the reason for a blue sky is cause molecules in the air scatters blue light from the sun, blue light has a short wavelength and so can travel very fast
the wavelength of blue light is 450 - 490nm which is shorter than red light this is the reason the sky is blue most time during the day
