The main difference between the phenomena of interference and diffraction is that:

1. diffraction is caused by reflected waves from a source whereas interference is caused due to the refraction of waves from a source.
2. diffraction is caused due to the interaction of waves derived from the same source, whereas interference is the bending of light from the same wavefront.
3. diffraction is caused due to the interaction of light from the same wavefront, whereas the interference is the interaction of two waves derived from the same source.
4. diffraction is caused due to the interaction of light from the same wavefront whereas interference is the interaction of waves from two isolated sources.
