Class 12th Physics 2017 Set1 Delhi Board Paper Solution
Explain two features to distinguish between the interference pattern in Young's double slit experiment with the diffraction pattern obtained due to a single slit.
| Interference | Diffraction |
| (i) Intensity of all bright fringes are same | Intensity falls with increasing order |
| (ii) Fringes width is equal | Fringes width decreasing with order |
| (iii) Source : Two coherent source,wavefront interface | secondary wavelets coming from different parts of same wavefront. |
