Difference between interference and diffraction

1.	Difference between interference and diffraction
Answer» INTERFERENCEIT IS DUE TO THE SUPERPOSITION OF TWO WAVES COMING FROM TWO COHERENT SOURCES.THE WIDTH OF THE INTERFERENCE BAND IS EQUAL.THE INTENSITY OF ALL MAXIMA (FRINGES) IS SAME. DIFFRACTIONIT IS DUE TO THE SUPERPOSITION OF SECONDARY WAVELETS ORIGINATING FROM DIFFERENT PARTS OF THE SAME WAVEFRONT.THE WIDTH OF THE DIFFRACTION BANDS IS NOT THE SAME.THE INTENSITY OF CENTRAL MAXIMUM MAXIMUM AND GOES ON DECREASING RAPIDLY WITH INCREASE OF ORDER OF MAXIMA.
