The change or deflection in a wave pattern of light or sound. Diffraction occurs when light waves pass through an opening or past an opaque barrier. The light is deflected, or bent, toward the obscuring side of the opening or barrier. Shorter wavelengths are deflected less than longer wavelengths. The overlap of the wavelengths can cause interference and in some cases produce a diffraction pattern of light and dark bands. | The change or deflection in a wave pattern of light or sound.

Description
The change or deflection in a wave pattern of light or sound. Diffraction occurs when light waves pass through an opening or past an opaque barrier. The light is deflected, or bent, toward the obscuring side of the opening or barrier. Shorter wavelengths are deflected less than longer wavelengths. The overlap of the wavelengths can cause interference and in some cases produce a diffraction pattern of light and dark bands.
