What does “Transverse nature” actually mean in Electromagnetic Waves, and why does it matter for NEET?
In a plane electromagnetic wave, electric field E and magnetic field B are perpendicular to each other and to the direction of propagation. Their cross-product direction E x B points along energy flow.
In simple words: In a plane electromagnetic wave, electric field E and magnetic field B are perpendicular to each other and to the direction of propagation. Their cross-product direction E x B points along energy flow. Getting Transverse nature clear matters because NEET questions on Electromagnetic Waves usually test this idea directly, not just a formula you memorised.
Key point
Transverse nature
Common mistake
drawing E or B along the direction of travel.
Memory tip
E, B and travel direction form three mutually perpendicular axes.
