wave-optics Question 12
Question: Q. 2. In what way is diffraction from a single slit related to the interference pattern in a double slit experiment? $R$ [O.D.Comptt. I, II, III, 2013]
Show Answer
Solution:
Ans. Relation between diffraction from a single slit to the interference pattern in a double slit experiment :
(i) If slit width in interference pattern is reduced to the size of wavelength of light used; the diffraction will also takes place along with interference.
(ii) The diffraction pattern is itself due to the interference of wavelength belonging to same but different order of spectrum. (AT). 3. Draw a graph showing the intensity distribution of fringes due to diffraction at single slit.
