Asman ka rang neela (blue) kyun hota hai, ise Class 5 aur Class 10 ke levels par explain karein?

Yeh topic Physics (Optics aur Atmospheric Science) se related hai, jo ke mere core Chemistry domain se thora bahar hai. Lekin main aapko dono levels par crisp and clear tareeqe se samjha deti hoon: ### 1. Class 5 Level: Suraj ki dhoop (sunlight) dekhne mein safaid lagti hai, lekin is mein Rainbow ke 7 rang chhupe hote hain. Hamaari hawa (atmosphere) mein chotay chotay particles aur gases mojood hoti hain. Blue colour bohot tezi se choti choti chhalangein maarta hai, is liye jab sunlight hawa se guzarti hai toh neela (blue) rang in particles se takra kar har taraf bikhar (scatter ho) jata hai. Isi bikhri hui neeli roshni ki wajah se asman blue nazar aata hai. ### 2. Class 10 Level: Sunlight darasall continuous spectrum of visible light ($VIBGYOR$) par mushtamil hoti hai. Jab sunlight Earth ke atmosphere mein enter hoti hai, toh hawa mein mojood gas molecules (jaise $N_2$ aur $O_2$) ka size light ki wavelength se kafi chota hota hai. Yahan **Rayleigh Scattering** ka process hota hai, jiske mutabiq scattering of light wavelength ki fourth power ke inversely proportional hoti hai: $I \propto \frac{1}{\lambda^4}$ Chunke Blue light ki wavelength ($\lambda$) Red light ke muqable mein bohot short hoti hai, is liye yeh atmosphere mein sabse zyada scatter hoti hai. Har direction se yeh scattered blue light hamari aankhon tak pohanchti hai, is wajah se sky blue dikhayi deta hai. [[SUGGEST_GROUP:Physics]]
