Complete topic list for Wave Optics in Kerala Board Class 12 Physics. Key concepts, sub-topics, and what to focus on for board exams.
Topics in Wave Optics
1. Huygens' Principle and Wave Propagation
- Each point on a wavefront acts as a source of secondary wavelets
- New wavefront is the envelope of all secondary wavelets
- Wavefront is perpendicular to direction of wave propagation
2. Interference of Light
- Redistribution of energy due to superposition of coherent waves
- Constructive interference: waves in phase (δ = 2nπ)
- Destructive interference: waves out of phase (δ = (2n+1)π)
3. Diffraction of Light
- Bending of light around obstacles/apertures of size comparable to wavelength
- Single slit produces central bright band with dimmer secondary maxima
- Central maximum width = twice the width of secondary maxima
4. Polarization of Light
- Restricts light vibrations to a single plane perpendicular to propagation direction
- Proves transverse nature of light waves
- Polaroid materials allow transmission in one plane only
