Class 12 · Chapter 11Dual Nature of Radiation and Matter
Light as particle (photoelectric effect); matter as wave (de Broglie).
1. Photoelectric Effect
- No emission below threshold frequency.
- Stopping potential depends on frequency, not intensity.
- Photocurrent ∝ intensity.
- Instantaneous.
2. Photon
eV nm.
3. Matter Waves
nm (electron)
Davisson–Germer experiment confirmed electron waves.
4. Key Points
- Work function in eV.
- Slope of V₀ vs ν graph = h/e.
- Heavier particle, shorter λ.
- Einstein's equation explains the effect.
Remember: Einstein equation | V₀ vs ν | λ = h/p
