Modern Physics-I — Syllabus & Topics
Topics covered in Modern Physics-I for JEE Advanced Physics.
Topics in Modern Physics-I
Dual Nature of Electromagnetic Waves
- Electromagnetic waves exhibit both wave and particle properties (wave-particle duality)
- Wave nature demonstrated by Young's double-slit experiment showing interference
- Particle nature demonstrated by photoelectric effect where light behaves as photons
Electromagnetic Spectrum
- Complete range of electromagnetic waves from γ-rays to radio waves
- Classified by wavelength/frequency and production method
- Visible light: 4000 Å to 7000 Å (violet to red)
Momentum and Radiation Pressure
- Electromagnetic waves carry linear momentum: p = E/c
- Radiation pressure on surface: p_rad = I/c (totally absorbed), p_rad = 2I/c (totally reflected)
- Force exerted by electromagnetic wave: F = (1/c)(ΔE/Δt)
de-Broglie Wavelength
- Matter exhibits wave-particle duality (de-Broglie hypothesis)
- de-Broglie wavelength: λ = h/p = h/(mv)
- For particle with kinetic energy K: λ = h/√(2mK)
