can we consider diffraction as a special case of interference?Explain.

IN INTERFERENCE THE TWO SLITS ACTS AS INDEPENDENT SOURCES OF LIGHT AND PRODUCE INTERFERNCE PATTERN BUT IN ADDITION TO THE INTEFERENCE PATTERN EACH SINGLE SLIT INVOLVED IN THE INTEFERENCE UNDERGOES DIFFRACTION....IF WE COVER ANY ONE OF THE SLITS THEN DIFFRACTION INSTED OF INTEFERENCE IS OBTAINED.BUT WHEN BOTH SLITS ARE OPEN WE USUALLY NEGLECT THE DIFFRACTION EFFECT
