3.9 understand that waves can be diffracted through gaps, and that the extent of diffraction depends on the wavelength and the physical dimension of the gap.

  • Less diffraction when the length of opening is greater than the wavelength
  • More diffraction when the length of an opening is less than the wavelength

 

  • Larger wavelength means larger diffraction
  • Smaller wavelength means smaller diffraction
