1.	In youngs double slit experiment, if the distances between the slits is made 3- folds the fringe width becomes
Answer» we know that, the fringe width β = \(\frac{\lambda D }{d}\) where λ = wavelength of light. D = distance b/w slits and screen. d = distance b/w slits. β \(\prec\) \(\frac{1}{d}\) it d become 3 folds. then β become \((\frac{1}{3})\) times.

Answer»

we know that, the fringe width β = \(\frac{\lambda D }{d}\)

where λ = wavelength of light.

D = distance b/w slits and screen.

d = distance b/w slits.

β \(\prec\) \(\frac{1}{d}\)

it d become 3 folds.

then β become \((\frac{1}{3})\) times.

Read carefully the passage and select the correct answer out of given four options:Biofertilizers are organisms that enrich nutrient quality of the soil. The important sources of biofertilizers are bacteria, fungi and cyanobacteria. The symbiotic association of Rhizobium with the root nodules of leguminous plants is the common example.
