26: Wave Optics

  • Page ID
    • 26.1: Superposition and Interference
      Interference is a phenomenon in which two waves superimpose to form a resultant wave of greater or lesser amplitude.
    • 26.2: Diffraction
      Huygens’s Principle states that every point on a wavefront is a source of wavelets, which spread forward at the same speed.
    • 26.3: Further Topics
      Thin film interference occurs when incident light waves reflected by the different layers of a thin film interfere and form a new wave.
    • 26.4: Applications of Wave Optics
      Microscopy helps us view objects that cannot be seen with the naked eye.
