monochromatic In a modified Young s double slit experiment a uniform and parallel beam of light of wavelength 6000 and intensity 10 W m is incident normally on two circular apertures A and B of radii 0 001 m and 0 002 m respectively A B F h A perfectly transparent film of thickness 2000 and refractive index 1 5 for the wavelength of 6000 is placed in front of aperture A see figure Calculate the power in watt received at the focal spot F of the lens The lens is symmetrically placed with respect to the aperture Assume that 10 of the power received by each aperture goes in the original direction
