1.	In the `YDSE` shown the two slits are covered with thin sheets having thickness `t` & `2t` and refractive index `2mu` and `mu` .Find the position (y) of central maxima. A. zeroB. `(tD)/(d)`C. `(-tD)/(d)`D. none of these
Answer» Correct Answer - B At the central maxima `Deltax=0` But upward shift `=((2mu-1)tD)/(d)` and Downward shift `=((mu-1)2tD)/(d)` So net shift `y=(tD)/(d)[2mu-1-2mu+2]impliesy=(tD)/(d)`
