⚡🌊 NEET 2018 PYQ – Direction of Propagation of EM Wave 🌊⚡

A very important and conceptual question from Electromagnetic Waves! 🎯

🔍 Key Concept:

Direction of propagation of electromagnetic wave is given by:

[
\vec{E} \times \vec{B}
]

👉 Electric field (( \vec{E} )) and Magnetic field (( \vec{B} )) are mutually perpendicular

👉 Direction of EM wave propagation is perpendicular to both

⸻

📌 Important Point:

✔ Use Right Hand Rule to find direction of propagation

✔ Point fingers along Electric field ((E))

✔ Curl towards Magnetic field ((B))

✔ Thumb gives direction of wave propagation

📌 Another Important Concept:

✔ In EM waves:
Electric field ⟂ Magnetic field ⟂ Direction of propagation

⸻

✅ Final Idea:

💡 Direction of EM wave is always along:

[
\vec{E} \times \vec{B}
]

⸻

✨ Shortcut Tip:
E cross B → Direction of wave 🎯

Very important NEET trick question 🎯
