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.

Is interference and diffraction are same?

Diffraction And Interference. The phenomena of diffraction occurs for all waves. ... They visibly change direction, or diffract, as they pass through the opening. Interference is the phenomena of two waves meeting and adding together to form a resulting wave that is the sum of the heights of each wave where they meet. .

In what way is diffraction related to interference?

The interference pattern in a double-slit experiment is modulated by diffraction from each slit. The pattern is the result of the interference of the diffracted wave from each slit.
