In young’s double slit experiment using monochromatic light the fringe pattern shifts by a certain distance on the screen when a mica sheet of refractive index 1.6 & thickness 1.964 microns is introduced in the path of one of the interfering waves. The mica sheet is then removed & the distance between the slits & the screen is doubled. It is found that the distance between the maxima (or minima) now is the same as the observed fringe shift upon the introduction of the miashat. Calculate the wavelength of the monochromatic light used in the experiment (in A°) ?
Correct answer is '5892'. Can you explain this answer?

In young’s double slit experiment using monochromatic light the ...
Shifting of fringes due to introduction of slab in the path of one of the slits, comes out to be;

Now, the distance between the screen & slits is doubled. 
Hence the new fringe width will become,

Given Δy = ω'


= 0.5892 x 10-6 m 
= 5892 A°
