An arrangement with a double slit, whose separation between slits is d = 0.15 mm, and a shield positioned 1 m from them is illuminated by a laser of λ = 450 nm. A very thin piece of thin glass is placed in front of one of the slits and it is verified that the diffraction pattern of the fringes is shifted. This is because the phase of the wave emerging in the glass is delayed by π. (a) Calculate the distance of the central maximum position from the original and (b) tell if it was shifted towards the slit with or without the glass. OPTIONS: ( ) - (a) 1.00 mm (b) to the side of the slit without the glass. ( ) - (a) 1.50 mm (b) to the slit side without the glass. ( ) - (a) 1.50 mm (b) to the side of the slit with the glass. ( ) - (a) 0.75 mm (b) to the side of the slit with the glass. ( ) - (a) 0.75 mm (b) to the slit side without the glass ( ) - (a) 1.00 mm (b) to the side of the slit with the glass.
