Electromagnetic Waves — Syllabus & Topics
Topics covered in Electromagnetic Waves for MHT-CET Physics.
Topics in Electromagnetic Waves
8.1 Introduction and Maxwell's Contributions
- Maxwell identified inconsistency in Ampere's circuital law when applied to time-varying currents
- Introduced concept of displacement current to resolve the inconsistency
- Formulated four fundamental equations (Maxwell's equations) describing electromagnetic phenomena
8.2 Displacement Current and Modified Ampere's Law
- Inconsistency arises when applying Ampere's law to charging/discharging capacitors
- For loop outside capacitor plates: magnetic field exists due to conduction current
- For loop between capacitor plates: no conduction current but magnetic field must be continuous
8.3 Maxwell's Four Equations
- Four fundamental equations describing all electromagnetic phenomena
- First equation: Gauss's law for electricity (∮ E⃗ · dS⃗ = q/ε₀)
- Second equation: Gauss's law for magnetism (∮ B⃗ · dS⃗ = 0)
8.4 Electromagnetic Waves - Generation and Properties
- Electromagnetic waves are transverse waves with E⃗ ⊥ B⃗ ⊥ direction of propagation
- Generated by accelerating charges (oscillating charges, alternating currents)
- Self-propagating: changing E produces B, changing B produces E
