^Wave optics
Light behaves as a wave when the size of obstacle is comparable with the wavelength of light. Wave optics branch explains the following phenomena
- Interference (i.e. non uniform distribution of energy when two or more light waves superpose)
- Diffraction (i.e. bending & spreading of light wavefronts on encountering obstructions of size comparable or smaller than its wavelength)
- Polarisation (i.e. restricting the vibrations of light to one plane)
