प्रश्न
State any one difference between interference of light and diffraction of light
Advertisements
उत्तर
| Interference | Diffraction |
| Interference is the result of the superposition of different waves | Diffraction is the result of the superposition of the light wave of the different part of the same wavefront. |
| Interference fringes are of the same width | Diffraction fringes are not of the same width |
| All the bright bands of equal intensity | The intensity of the central maximum is the highest and the secondary maximum are of decreasing intensities. |
| The regions of minimum intensities are dark. |
The region of minimum intensities is not perfectly dark. |
| Both dark and bright bands are equally spaced. |
Dark bands on either side of the central bands are equally spaced but bright bands are not equally spaced |
| Large numbers of the band are obtained | Few bands are obtained |
| Resolving power of optical instrument is not related to interference. |
Resolving power of optical instrument is related to diffraction |
