What is diffraction of light ? Differentiate between diffraction and interference

Diffraction of light is the phenomenon of bending of light round the corners and spreading into the regions of the geometrical shadow.

Diffraction	Interference
The phenomenon of interaction of light coming from different parts of the same wave front is called diffraction.	The phenomenon of non uniform distribution of light energy (wave) due to the superposition of coherent sources of light is called interference.
In diffraction, the widths of fringes are not equal.	In interference, the width of fringes are equal.
Bands are very less in number.	Bands are very large in number.
Dark fringes in diffraction are not completely dark.	Dark fringes in interference are perfectly dark.
