Key Topics to Revise

1

Huygens Principle and Wave Theory

  • Huygens principle states that every point on a wavefront acts as a source of secondary wavelets
  • The new wavefront is formed by the envelope of all secondary wavelets
  • Wave theory correctly predicted that light travels slower in denser media
2

Coherent Sources and Interference

  • Coherent sources maintain constant phase difference over time
  • Interference occurs when two or more waves superpose at a point
  • Constructive interference occurs when path difference = nλ
3

Young's Double Slit Experiment

  • Young's experiment proved the wave nature of light conclusively
  • Two coherent sources are created by illuminating two slits with single source
  • Bright and dark fringes are equally spaced on the screen
4

Single Slit Diffraction

  • Single slit produces diffraction pattern with central bright maximum
  • Pattern has alternating bright and dark regions
  • Central maximum is twice as wide as other maxima
