dear kushwaha...........

Diffraction refers to various phenomena which occur when a wave encounters an obstacle. In classical physics, the diffraction phenomenon is described as the apparent bending of waves around small obstacles and the spreading out of waves past small openings. Similar effects occur when a light wave travels through a medium with a varying refractive index, or a sound wave travels through one with varying acoustic impedance. Diffraction occurs with all waves, including sound waves, water waves, and electromagnetic waves such as visible light, X-rays and radio waves. As physical objects have wave-like properties (at the atomic level), diffraction also occurs with matter and can be studied according to the principles of quantum mechanics. Italian scientist Francesco Maria Grimaldi coined the word "diffraction" and was the first to record accurate observations of the phenomenon in 1665.

when light passes sharp edges or goes through narrow slits the rays are deflected and produce fringes of light and dark bands this is called Diffraction.

suppose a slit having two small holes . when waves moving towards this slit , first they bend and after passes through the small hole and after spreading into many waves . this phenomenon is called diffraction.  do u like my simply answer?

the bending of light takes place at the edges when touches the object or obstacle which is in the path of light wave is called diffraction.
