The main difference in the phenomenon of interference and diffraction in light waves is that
1
Diffraction is due to interaction of light from the same wave-front whereas interference is the interaction of waves from two isolated sources
2
Diffraction is due to interaction of light from same wavefront, whereas the interference is the interaction of two waves derived from the same source
3
Diffraction is due to interaction of waves derived from the same source, whereas the interference is the bending of light from the same wavefront
4
More than one of the above
5
None of the above
