Prakash ka Pravartan

Prakash Ki Parabhav

Prakash ka Pravartan:
- Prakash ka pravartan, yaani light refraction, ek prakriya hai jismein prakash ki kirnein ek madhyam se doosre madhyam mein girne par unka raasta badal jati hain.
Snell's Law:
- Refraction ka niyam, Snell's Law, kehta hai:
  - n1 * sin(θ1) = n2 * sin(θ2)
- Yahaan, n1 aur n2 do alag madhyamon ki refractive indices hain, aur θ1 aur θ2 unka incidence aur refraction angle hain.
Madhyam ki Prakriti:
- Prakash ka pravartan do madhyamon ke beech ke refractive index par nirbhar karta hai.
- Alag-alag madhyamon (jaise hawa, paani, glass) ka alag refractive index hota hai.
Prakash ka Pravartan aur Chashma:
- Chashme (lenses) mein prakash ka pravartan hota hai.
- Convex lens (sakaratmak) aur concave lens (nikaratmak) alag tarike se light ko bend karte hain.
Prakash ki Bending:
- Jab prakash ek madhyam se doosre madhyam mein pravesh karta hai (jaise hawa se paani), to uska raasta badalta hai aur yah bending kehlata hai.
- Prakash ka bending jab zyada hota hai, tab yah dispersion (vibhajan) bhi kar sakta hai, jisse rainbow ya prism ke rang dikhai dete hain.
Prakash ki Speed:
- Prakash ki speed alag-alag madhyamon mein alag hoti hai.
- Vacuum mein prakash ki speed sabse adhik hoti hai (approximately 3 x 10^8 m/s).
Prakash ka Pravartan aur Aankhein:
- Aankhon mein chashma ya contact lenses ka istemal hota hai jisse light ka pravartan sahi kiya jata hai taaki hum spasht dekh saken.
Practical Applications:
- Optical fibers mein communication ke liye prakash ka pravartan ka istemal hota hai.
- Lenses ka istemal camera, microscopes, aur telescopes mein hota hai.
Refraction ke Prabhav:
- Samudrik jeevon mein prakash ke pravartan se dikhayi dene wale prabhav, jaise underwater visibility, kaafi mahatvapurn hote hain.
- Prakash ka pravartan kuch phenomena jaise mirage aur total internal reflection mein bhi dekha jaata hai.

Prakash ka Pravartan

Prakash ka pravartan ek prakriya hai jismein light rays ek madhyam se doosre madhyam mein girne par apna raasta badal deti hain.
Snell's Law: Refraction ke liye niyamaat:
- n1 * sin(θ1) = n2 * sin(θ2)
- n1 aur n2 madhyam ke refractive indices hain, aur θ1 aur θ2 ka incidence aur refraction angle hai.
Prakash ka pravartan madhyamon ke refractive index par nirbhar karta hai; alag-alag madhyamon (hawa, paani, glass) ka refractive index alag hota hai.
Chashma aur Lenses: Chashma aur lenses meinprakash ka pravartan hota hai.
- Convex lens (sakaratmak) prakash ko ek bindu ki aur bend karta hai, jabki concave lens (nikaratmak) ise vistar mein failata hai.
Prakash jab ek madhyam se doosre madhyam mein pravesh karta hai, jaise hawa se paani, to uska raasta badalta hai; is prakariya ko bending kehte hain.
Zyada bending se dispersion ya vibhajan ho sakta hai, jo rainbow ya prism ke rang dikhai deta hai.
Prakash ki speed alag-alag madhyamon mein alag hoti hai; vacuum mein yah sabse adhik hoti hai (3 x 10^8 m/s).
Aankhon mein chashma ya contact lenses ka istemal hota hai taaki light ka pravartan sahi ho aur dekhne mein spashtata aaye.
Practical Applications:
- Optical fibers mein communication ke liye prakash ka pravartan ka istemal hota hai.
- Lenses ka istemal cameras, microscopes, aur telescopes mein kiya jata hai.
Refraction ke Prabhav:
- Samudrik jeevon mein dikhayi dene wale prabhav, jaise underwater visibility, kaafi mahatvapurn hote hain.
- Prakash ka pravartan kuch phenomena, jaise mirage aur total internal reflection, mein bhi dekha jata hai.
