🌈🔬 NEET 2018 PYQ – Angular Fringe Width & Separation of Slits 🔬🌈

A very important and concept-based question from Wave Optics! 🎯

🔍 Key Concept:

Angular fringe width in Young’s Double Slit Experiment depends on:

[
\theta = \frac{\lambda}{d}
]

👉 Where:
• λ = wavelength of light
• d = separation between slits

⸻

📌 Important Point:

If slit separation increases →

✔ Angular fringe width decreases

⸻

⸻

📌 Another Important Concept:

If slit separation decreases →

✔ Fringes become wider

⸻

✅ Final Idea:

💡 Fringe width and slit separation are inversely proportional

⸻

✨ Shortcut Tip:
More slit separation → Narrow fringes
Less slit separation → Wider fringes 🎯

Very important NEET trick question 🎯
