The difference between interference and diffraction are as follows:
SN | Interference | Diffraction |
1. | Interference occurs due to wavelets of different wavefronts. | Diffraction occurs due to the superposition of wavelets of the different parts of the same wavefront. |
2. | In interference, bands may be of equal width. | Diffraction fringes are not of the same width. |
3. | Points of minimum intensity are perfectly dark. | Points of minimum intensity are not perfectly dark. |
4. | All bright bands are of uniform intensity. | All bright bands are not of the same intensity. |
5. | Bands are larger in number. | Bands are fewer in number. |
