DIFFRACTION

DIFFRACTION

1. LIGHT

   • Light is diffracted
     • if it passes through a narrow slit comparable in size to its wavelength
     • if it passes through a narrow slit comparable in size to its wavelength.
       • However, the effect is not obvious as the size of the slit increases. (BCS :because the wavelengths of light are very short.)

2. SOUND

   • Sound diffracting around corners (so allowing us to hear others who are speaking to us from adjacent rooms.)
