  • Reflection, Refraction and Diffraction
    • Reflection
      • When waves are incident on the surface they can be reflected, transmitted or absorbed.
      • An echo is heard when sound is reflected.
      • When light rebounds of a surface and changes direction. It is reflected
    • Refraction
      • Refraction is the change of speed and direction of a wave when it goes from one medium to another.
        • Refraction doesn't happen if the waves cross the boundary at an angle of 90°
          • In that case they carry straight on
    • Diffraction
      • Diffraction occurs when a wave passes through a narrow opening.
        • Diffraction is greatest when the gap is the same width as the wavelength.
