Topics covered in Electromagnetic Waves for NEET-UG Physics.
Topics in Electromagnetic Waves
1
Fundamentals of Electromagnetic Waves
- Electromagnetic waves are produced by accelerating charges or oscillating electric and magnetic fields
- Electric field (E) and magnetic field (B) oscillate in phase and are mutually perpendicular
- The direction of wave propagation is given by E × B (right-hand rule)
2
Maxwell's Equations and Displacement Current
- Ampere's law fails for time-varying currents due to inconsistency in capacitor circuits
- Maxwell introduced displacement current to resolve this inconsistency
- Displacement current flows through regions where electric field is changing
3
Energy and Intensity of EM Waves
- Energy in EM waves is equally distributed between electric and magnetic fields
- Energy density depends on field amplitudes squared
- Intensity is energy flux - energy crossing unit area per unit time
4
Momentum and Radiation Pressure
- EM waves carry momentum proportional to their energy
- Momentum transfer occurs when waves are absorbed or reflected
- Radiation pressure is momentum transferred per unit area per unit time
