Welcome to the Killer Series! Is video mein hum Class 12 Physics ke Chapter 8 Electromagnetic Waves (EM Waves) ke pichle 10 saalon ke sabse important Previous Year Questions (PYQs) ko detail mein solve karenge.

Electromagnetic Waves ek small but highly scoring chapter hai. Is session mein humne cover kiya hai Displacement Current, Properties of EM Waves, aur Electromagnetic Spectrum (Uses & Production) ke tricky memorization-based questions aur numericals.

📝 Is Video mein aap sikhenge:
Displacement Current ka concept aur formula.
Relation between Electric (E) & Magnetic (B) Fields ($c = E_0/B_0$).
Electromagnetic Spectrum (Radio to Gamma rays) ke Uses aur Production.
Wavelength aur Frequency range ke important sawal.
Energy Density aur Speed of Light se jude numericals.
Last 10 Years ke most repeated Board Questions.
