In YDSE, a thin mica sheet of thickness

2 \times 10^{-6} \mathrm{~m}

and refractive index

(\mu=1.5)

is introduced in the path of the wave in front of the slit above the central line of the screen. The wavelength of the wave used is

5000 \mathop {\text{A}}\limits^ \circ

. The central bright maximum will shift

View answer and explanation

Correct option: A

2 fringes upward

Option A (2 fringes upward) is correct because the central bright maximum shifts upward by a distance equal to 2 fringe widths when the mica sheet is introduced.
