In a modified Young's double slit experiment a monochromatic uniform and parallel beam of light of wave length 6000Å and intensity `(10/pi)Wm^(-2)` is incident normally on two circular apertures A and B of radii 20009Å and refractive index 1.5 for the wavelength of 6000Å is placed in front of aperture. A. Calculate the power (in watt) received at the focal spot F of the lens. The lens is symmertrically placed with respect to the apertures. Assume that 10% of the power received by each aperture goes in the originally direction and is brought to the focal spot.

In a modified Young's double-slit experiment, a monochromatic uniform and parallel beam of light of wavelength 6000 Å and intensity (10//pi) W m^(-2) is incident normally on two circular apertures A and B of radii 0.001 m and 0.002 m, respectively. A perfectly transparent film of thickness 2000 Å and refractive index 1.5 for the wavelength of 6000 Å is placed in front of aperture A (see the figure). Calculate the power (in mW) received at the focal spot F of the lens. Then lens is symmetrically placed with respect to the aperture. Assume that 10% of the power received by each aperture goes in the original direction and is brought to the focal spot.
