Dear students agar aap class 12 ke student hai to aap total internal reflection ka name jarur sune hoge. Agar aap total internal reflection ka name nhi sune hai to aap yah janiye ki total internal reflection class 12 ke optics chapter me padhna hai. Yah aapko class 10 ke light chapter me bhi mil jaaega to student aaj ham total internal reflection ke bare me detail knowledge prapt kar lete hai.
Aap jaisa ki image me dekh rhe hai ki jab light denser medium se rarer medium me jaa rha hai to bah normal se away bend kar ja rha hai. Agar ham angle of incidence ko continuous badhate jaye to angle of refraction ka bhi value lagatar badhta jaega. Isi tarah ek aisa bhi time aaega jab light bend karte-karte surface ko bilkul touch karke pass karega. Jab light surface ko bilkul touch kar ke pass karta hai to us time ke angle of incidence ko critical angle kahte hai hindi me critical angle ko krantik kon kha jata hai. Jab incidence angle ko critical angle se bhi jyada kiya jata hai to light refract na hokar reflect ho jata hai. Isi ghatna ko total Internal reflection kha jata hai.
(1) Ray of light must should be travel from denser to rarer medium:- Total internal reflection ke lie yah 1st condition hai. jab light denser se rarer medium me jata hai to uska total internal reflection ho sakta hai lekin jab light rarer se denser medium me jata hai to uska kabhi bhi total internal reflection nhi hoga kyonki jab light rarer se denser medium me jata hai to light normal ke towards bend karta hai islie iska total internal reflection kabhi bhi possible nhi hai.
(2) Angle of incidence should be greater than critical angle:- Ham upar figure me clear dekh sakte hai ki jab tak angle of incidence ka value critical angle se chota hota hai tab tak Total internal reflection nhi hota hai lekin jab angle of incidence ka value critical angle se bada hota hai to total internal reflection hone lgta hai. Islie yah jaruri hai ki total internal reflection ke lie angle of incidence ka value critical angle se jyada hona chahiea.

What is total internal reflection (Purn antrik pravartan kya hai)
Friends jaisa ki ham jante hai jab light ek transparent medium par incident karti hai to us light ka refraction hota hai lekin kuch condition me light ka refraction na hokar light ka reflection ho jata hai. Isi ghatna ko total internal reflection kaha jata hai. lekin hame detail me janna hoga ki total internal reflection kya hota hai. |

Definition of total internal reflectionWhen light ray goes from denser to rarer medium and if angle of incidence is greater then critical angle then light doesn't refract rather it reflects this phenomenon is known as total internal reflection.
Condition of total internal reflection
Total internal reflection ke lie kuch condition bahut jaruri hai agar light total internal reflection ke condition ko follow nhi karta hai to uska total internal reflection nhi hoga. Islie total internal reflection ke dono condition ko follow karna bahut hi jaruri hai.(1) Ray of light must should be travel from denser to rarer medium:- Total internal reflection ke lie yah 1st condition hai. jab light denser se rarer medium me jata hai to uska total internal reflection ho sakta hai lekin jab light rarer se denser medium me jata hai to uska kabhi bhi total internal reflection nhi hoga kyonki jab light rarer se denser medium me jata hai to light normal ke towards bend karta hai islie iska total internal reflection kabhi bhi possible nhi hai.
(2) Angle of incidence should be greater than critical angle:- Ham upar figure me clear dekh sakte hai ki jab tak angle of incidence ka value critical angle se chota hota hai tab tak Total internal reflection nhi hota hai lekin jab angle of incidence ka value critical angle se bada hota hai to total internal reflection hone lgta hai. Islie yah jaruri hai ki total internal reflection ke lie angle of incidence ka value critical angle se jyada hona chahiea.
the MoP, with the merit, the Collegium should consider the suitability of a person keeping in mind the superiority of the Supreme Court. It looks at the seniority of the judges in the seniority list of the judges of the All India High Court and attempts to ensure the balanced representation of various high courts widely.
