सभी स्टूडेंट्स से अनुरोध है कि नीरज sir की class को ज्यादा से ज्यादा like व share करें ताकि sir खुश और motivate होकर हमारे लिए ओर ज्यादा बेहतरीन pdf कंटेंट लेकर आएं।मैं sir को पिछले एक साल से फॉलो कर रहा हूँ sir बहुत बढ़िया पढ़ाते हैं इससे भी अच्छी बात यह है कि sir कभी भी पुरानी pdf repeat नहीं करते बल्कि और कंटेंट add करके एक नई बेहतरीन pdf लेकर आते हैंवो भी बिल्कुल फ्री, ऐसे teacher को मेरा दिल से प्रणाम और धन्यवाद
सर पहले मैं science को रटता था तो exam time मे भूल जाता था। lekin ab aap se padhane ke baad mujhe science easy lagne lagi hai kyoki sir aap chijo ko feel karwate ho. Or sir mene you tube par science ke anya teacher ko bhi padhate dekha hai lekin sir aap un sab me best padhate ho
Sichha Bo serani Ka dudh he jo peta he bahi dhahanata he Eis des ko aap jese teacher ki sakat jarurat he Aap jese teacher des ko mahan Bana sakate he 🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏
सायन्स पहले बहोत हार्ड लगती थी। आपके वजह से इंटरेस्टिंग लग रही है आज कल...💐थैंक्स sir जी.. अगर सेलेक्शन ले लू Group D में तो आपके चरणपर्श करने का मौका मुझे मिलेगा तो खुद को भाग्यवान समुझे गा मे....💐💐

9:52 midium
14:15 Denser medium
15:35 Rare Medium
18:00 when light goes Rare to Denser Medium ( it's bents toward the normal )
19:36 when light goes denser to rare medium ( it's bents far from the normal )
21:00 light spreed max in vaccum 3x10⁸ m/s
23:10 Refective Index ( μ)
optical density ↑ light spreed ↓ μ ↓
27:24 Relation of μ ∝ 1/optical density of this medium
μ ∝ ¹/ᵥ
μ ∝ Optical density
30:27 How to find out Refractive Index
μₘ= ᶜ/ᵥ
μₘ medium Refrective Index
