Modified YDSE!

A Young's Double Slit Experiment (YDSE) is performed. In the figure, the light is entering from water with refractive index \(\dfrac{4}{3}\). There is a rectangular slab in front of \(S_2\) which is filled with water.

Find the vertical position of central maxima.

Details and Assumptions:

  • Monochromatic light is used.

  • \(d=0.3 \text{ mm}\)

  • Thickness of slab \(t=0.41\text{ mm}\).

  • \(D=1\text{ m}\).

  • Consider the center of \(S_1\) and \(S_2\) to be the origin and the vertical distance being measured from it.

  • Use SI units.
