Key Topics to Revise
Huygens Principle and Wavefronts
- A wavefront is the continuous locus of all particles vibrating in the same phase at any instant
- Three types of wavefronts: spherical (point source), cylindrical (linear source), and plane (distant source)
- Huygens Principle: Every point on a primary wavefront acts as a source of secondary wavelets
Coherence and Superposition
- Coherent sources maintain constant phase difference over time
- Superposition principle: resultant displacement is vector sum of individual displacements
- Constructive interference occurs when waves are in phase (path difference = nλ)
Young's Double Slit Experiment
- First experiment to demonstrate wave nature of light conclusively
- Uses single source with double slit to create coherent sources
- Bright fringes occur at positions where path difference = nλ
Thin Film Interference
- Colors in soap films and oil layers are due to thin film interference
- Two reflections occur: one at top surface, one at bottom surface
- Path difference depends on film thickness and refractive index
