JEE Main Wave Optics: Superposition Amplitude Formula 💡
❓ Concept 🎬 Wave Optics – Resultant Amplitude in 60 Sec Do light waves mil rahi hain… par amplitude seedha add hoga ya cancel? 👉 Answer hamesha phase difference batata hai! 🌊✨ Wave optics mein calculation kam, vector understanding zyada important hota hai 🔥 🖼️ Concept Image ✍️ Short Explanation Superposition ka matlab simple addition nahi hota. Light waves → electric field vectors hote hain. Isliye: 👉 Vector addition apply hota hai. 🔹 Step 1 — Superposition Principle (FOUNDATION 💯)** When two waves meet at a point: E resultant = E 1 + E 2 But important: ⚠️ Vector sum , not simple arithmetic sum. 🔹 Step 2 — Same Frequency, Same Direction Given waves: E 1 = E 0 sin ( ω t ) E_1 = E_0 \sin(\omega t) E 2 = E 0 sin ( ω t + ϕ ) E_2 = E_0 \sin(\omega t + \phi) ✔ Same ω \omega ⇒ stable interference ✔ Same direction ⇒ direct vector addition 🔹 Step 3 — Phase Difference Controls Everything Different cases: ϕ = 0 \phi = 0 → Maximum const...
