Kya Kabhi Socha Aapne?
Subah uthte hain suraj nikla hota hai din shuru hota hai. Shaam hoti hai suraj dhalta hai raat aa jaati hai. Yeh silsila rozana chalta rehta hai lekin kya kabhi socha ke yeh hota kaise hai?
Kya suraj sach mein aata jaata hai ya kuch aur ho raha hai?
Aaj hum bilkul simple andaz mein samjhenge ke din aur raat kaise hote hainaur is ke peeche kya science hai!
Sabse Pehli Baat Suraj Nahi Chalata
Bahut se log sochte hain ke suraj subah aata hai aur shaam ko chala jaata hai lekin yeh bilkul ghalat hai!
Suraj nahi chalta Zameen khud ghoomti hai.
Yeh ek bohat zaroori baat hai jo samajhni chahiye. Suraj asal mein apni jagah par hai ya yun kahein ke suraj apni jagah par ghoom raha hai lekin Zameen ke scale par suraj fixed lagta hai. Zameen apni axis par ghoomti rehti hai aur is ghoomne ki wajah se kabhi hamaari taraf suraj ki roshni aati hai aur kabhi nahi aati.
Jis waqt hamaari taraf suraj ki roshni hoti hai woh din hota hai. Jis waqt hamaari taraf suraj ki roshni nahi hoti woh raat hota hai. Itna simple hai yeh concept!
Zameen Ki Axis Ek Khaas Jhukao
Zameen apni axis par ghoomti hai lekin yeh axis bilkul seedhi nahi hai. Zameen ki axis roughly 23.5 degree jhuki hui hai.
Yeh jhukao bilkul seedha upar neeche nahi balke ek taraf jhuka hua hai. Aur yahi jhukao seasons yaani mausamon ki wajah bhi hai lekin aaj hum sirf din aur raat par focus karenge.
Zameen ki axis ke dono siron ko North Pole aur South Pole kehte hain. Zameen in dono poles ke darmiyan se guzarne wali ek khayal ki line ke gird ghoomti hai.
Zameen Ka Rotation Ek Din Mein Ek Chakkar
Zameen apni axis par ek poora chakkar roughly 24 ghante mein lagati hai yahi hamaara ek din hai.
Zameen west se east ki taraf ghoomti hai isliye suraj hamesha east mein nikalta aur west mein dubta nazar aata hai. Asal mein suraj nahi chalta Zameen ghoomti hai lekin humein suraj chalta hua lagta hai.
Agar aap Zameen ko upar se dekhen North Pole ki taraf se toh Zameen anti-clockwise yaani ulti ghadi ki taraf ghoomti nazar aayegi. South Pole ki taraf se dekhen toh clockwise nazar aayegi.
Zameen ki ghoomne ki speed bohat zyada hai equator par roughly 1,670 kilometer per ghante! Lekin kyunke hum bhi Zameen ke saath ghoom rahe hain hume koi movement feel nahi hoti.
Din Aur Raat Ka Poora Process
Ab bilkul step by step samajhte hain ke din aur raat kaise hote hain.
Suraj ek bohat bada aur roshan star hai woh apne gird sab taraf roshni phailata rehta hai. Zameen suraj ke gird chakkar lagati hai aur saath hi apni axis par bhi ghoomti rehti hai.
Jis waqt Zameen ka jo hissa suraj ki taraf hota hai us hisse par din hota hai suraj ki roshni seedhi pad rahi hoti hai. Usi waqt Zameen ka doosra hissa suraj se door hota hai wahan raat hoti hai suraj ki roshni nahi pohonchti.
Yeh situation hamesha change hoti rehti hai kyunke Zameen ghoom rahi hai. Jab Pakistan mein din hota hai toh America mein raat hoti hai. Jab Australia mein subah hoti hai toh Europe mein raat hoti hai.Yeh sab Zameen ke ghoomne ki wajah se hota hai.
Ek simple misaal ek oraur use torch ki roshni mein rakhein. Orange ka jo hissa torch ki taraf hai woh roshan hoga wahan din hai. Doosra hissa andhera hoga wahan raat hai. Ab orange ko apni jagah par ghoomayein roshni aur andhere ka hissa badlta jaayega. Bilkul yahi Zameen ke saath hota hai!
Suraj Ka Ugna Aur Dubna
Jab Zameen ghoomti hai toh alag alag jagahon par suraj alag alag waqt par nikalta aur dubta nazar aata hai.
Jab aapka علاقہ ghoomte ghoomte suraj ki taraf aata hai toh suraj nikalte hua nazar aata hai yeh subah hai. Jab aapka Ilaaqa seedha suraj ke saamne hota hai roshni seedhi upar se padti hai yeh dopahar hai. Jab aapka Ilaaqa ghoomte ghoomte suraj se door hone lagta hai suraj dubta hua nazar aata hai yeh shaam hai. Aur jab aapka علاقہ bilkul suraj se door ho jaata hai poori raat hoti hai.
Subah Aur Shaam Ka Khubsoorat Rang
Jab suraj nikalta ya dubta hai toh aasman orange، pink، aur laal rang ka kyun hota hai?
Is ka jawab hai scattering of light. Suraj ki roshni alag alag wavelengths ki hoti hai violet، blue، green، yellow، orange، laal yeh sab milkar safed roshni banaate hain.
Jab suraj seedha upar hota hai toh roshni seedhi atmosphere se guzarti hai aur aasman neela nazar aata hai kyunke blue wavelength zyada scatter hoti hai. Lekin subah aur shaam ko suraj ek angle par hota hai roshni zyada atmosphere se guzarti hai blue aur violet wavelengths scatter ho jaati hain aur sirf orange aur laal wavelengths ziyada pohonchti hain isliye aasman orange aur laal rang ka nazar aata hai.
Yahi wajah hai ke subah aur shaam ka manzar itna khubsoorat hota hai!
Raat Ka Andhera Kyun Hota Hai
Yeh ek simple sawaal lagta hai lekin iska jawab thoda interesting hai.
Raat mein andhera isliye hota hai kyunke suraj ki seedhi roshni hamaari taraf nahi hoti. Lekin Chaand bhi hota hai raat mein Chaand ki roshni Kahan se aati hai?
Chaand khud nahi chamakta Chaand suraj ki roshni reflect karta hai. Jis tarah ek sheesha roshni reflect karta hai usi tarah Chaand bhi suraj ki roshni ko reflect kar ke Zameen par dal deta hai. Isliye raat mein Chaand nazar aata hai.
Lekin Chaand ki reflect ki hui roshni suraj ki seedhi roshni se bohat kam hoti hai isliye raat mein itna andhera rehta hai.
Time Zones Har Jagah Waqt Alag Kyun Hota Hai
Kyunke Zameen ghoom rahi hai aur alag alag jagahon par alag alag waqt par din aur raat hoti hai isliye poori duniya mein ek hi waqt nahi ho sakta. Isliye time zones banaye gaye hain.
Poori duniya ko roughly 24 time zones mein divide kiya gaya hai ek time zone ek ghante ka farq rakhta hai. Kyunke Zameen 24 ghante mein 360 degree ghoomti hai toh har ghante mein roughly 15 degree ghoomti hai toh har 15 degree par ek time zone hota hai.
Pakistan UTC +5 time zone mein hai matlab Pakistan ka waqt Greenwich Mean Time yaani GMT se 5 ghante aage hai. Jab Pakistan mein dopahar 12 baj rahi hoti hai to London mein subah ke 7 baj rahe hote hain aur New York mein raat ke 2 baj rahe hote hain.
Polar Day Aur Polar Night Ek Ajeeb Manzar
Zameen ki axis 23.5 degree jhuki hone ki wajah se kuch ajeeb phenomena bhi hote hain.
Polar Day: Norway، Finland aur doosre countries mein jo North Pole ke qareeb hain garmiyon mein suraj bilkul Nahi dubta 24 ghante roshni rehti hai! Is phenomenon ko midnight sun kehte hain. Imagine karein raat ke 12 baj rahe hain aur bahar din jaise roshni hai!
Polar Night: Usi tarah سردیوں mein North Pole ke qareeb Ilaaqon mein suraj bilkul ni nikalta poore 24 ghante andhera rehta hai! Yeh polar night kehlata hai.
Pakistan mein yeh phenomena nahi hote kyunke Pakistan equator ke qareeb hai lekin Shimla aur dusre high latitude Ilaaqon mein garmiyon aur saardiyon mein din raat ka farq kaafi zyada hota hai.
Ramzan Mein Roza Aur Waqt Pakistan Ka Perspective
Pakistan mein din aur raat ka topic Ramzan mein aur bhi zaroori ho jaata hai kyunke roza suraj nikaalne se suraj dubbe tak hota hai.
Pakistan mein garmiyon mein din lambe hote hain roughly 14 se 15 ghante aur saardiyon mein chhote roughly 10 se 11 ghante. Yeh farq Zameen ke jhukao aur suraj ke gird Zameen ki position ki wajah se hota hai.
Jab Pakistan mein garmiyon mein Ramzan hota hai toh roza kaafi lamba hota hai aur saardiyon mein hota hai toh chhota. Yeh sab is liye hai kyunke Zameen suraj ke gird ek jagah nahi rehti balke ghoomti rehti hai.
Ek Din 24 Ghante Kyun Hota Hai
Hum sochte hain ke ek din exactly 24 ghante ka hota hai lekin yeh thoda interesting hai.
Asal mein Zameen apni axis par ek chakkar roughly 23 ghante 56 minutes aur 4 seconds mein lagati hai yeh sidereal day kehlata hai. Lekin hamaara ek din 24 ghante ka kyun hota hai?
Kyunke Zameen apni axis par ghoomne ke saath saath suraj ke gird bhi ghoom rahi hai toh ek din mein thoda extra time lagta hai taake suraj wapas bilkul usi angle par nazar aaye. Yeh extra roughly 4 minutes ka fark hai. Is liye hamaara practical din 24 ghante ka hota hai.
Aakhri Baat Ek Chota Chakkar Badi Zindagi
Din aur raat Zameen ke apni axis par ghoomne ki wajah se hote hain yeh ek bohat simple lekin bohat powerful concept hai.
Ek chhota sa 24 ghante ka chakkar subah، dopahar، shaam، raat phir subah yeh silsila billions of saalon se chal raha hai aur shayad billions of saalon tak chalta rahega.
Agli baar jab subah uthein aur suraj nikalte dekhein yaad karain ke asal mein suraj Nahi aaya aap khud Zameen ke saath ghoomte ghoomte suraj ki taraf aa gaye!
