Is Diffraction the Same as Interference?

Interference refers to the phenomenon where two waves of the same kind overlap to produce a resultant wave of greater, lower, or the same amplitude. Diffraction is defined as the bending of a wave around the corners of an obstacle or aperture.

Is there interference in diffraction?

Diffraction is the tendency of a wave emitted from a finite source or passing through a finite aperture to spread out as it propagates. Diffraction results from the interference of an infinite number of waves emitted by a continuous distribution of source points.

In what way is diffraction related to interference?

(a) If the width of each slit is comparable to the wavelength of light used, the interference pattern thus obtained in the double slit experiment is modified by diffraction from each of two slits.
