The difference between interference and diffraction are as follows:
SN | Interference | Diffraction |
1.` | It is due to the superposition of wavelets of different wavefronts. | It is due to the superposition of wavelets of the different parts of the same wavefront. |
2. | In interference, bands may be of equal width. | In 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 the bright bands are of uniform intensity. | All bright bands are not of the same intensity. |
5. | Bands are large in number. | Bands are few in number. |
