Query: You have told that first principal focus of concave lens obtained at the right side in your diagram and it is F1 but it is slightly confusing from NCERT page given below. or Can you explain NCERT figure.9.19. NCERT -page-326: The focus on the the side of the the source of light is called the first Focal Point, where is the other is called the second Focal Point.
Kyu 2 focus 1st and 2nd define hota hai? Hum log jante hai ki light always same path follow karta hai jab opposite side se travel karta hai. Iska matlab hua 1st and 2nd focus always same. To hum log kyu 2 focus define karte hai??
Assam Live, Baar baar negative comment karne se kya fayda??? Bore hone ke baad bhi aap dusre videos me jaakar negative comment kar rahe hain. Bore ho gaye to aapko dusre videos nahi dekhni chahiye. Kabhi kah rahe hain ki aawaz kharab hai, kabhi gaaliya de rahe hai.... Negative comment ke pais mil rahe hain to thik hai, par fokat me kar rahe hain to SHAME ON YOU.
