Diffraction

Diffraction is the deviation of waves from straight-line propagation due to an obstacle or through an aperture, without any change in their energy. Diffraction is the same physical effect as interfere
The diffraction pattern (Airy disc) of a red laser beam projected onto a plate after passing through a small circular aperture in another plate
Single-slit diffraction in a circular ripple tank
Diffraction pattern from a square aperture
Optical diffraction pattern
In optics, the Fraunhofer diffraction equation is used to model the diffraction of waves when the diffraction pattern is viewed at a long distance from the diffracting object, and also when it is view
Computer simulation of Fraunhofer diffraction by a rectangular aperture
Single and double slit diffraction – slit separation is 0.7mm and the slit width is 0.1mm.
