In a Young's double slit experiment two narrow slit 0.8 mm apart are illuminated by the same source of yellow light (l = 5893 Å). If distance between slits and screen is 2m then separation between adjacent bright lines will be
Answer & explanation
Correct answer: option 3
$ \beta = \frac{\lambda D}{d} = \frac{5893\times 10^{-10}\times 2}{8\times 10^{-4}} = 0.1473cm$
