JEE Mains Model Paper 5

In a double slit experiment, the separation between slits is d = 0.25 cm and thedistance of the screen D = 100 cm from the slits. If the wavelength of light usedis l = 6000 A° and I0 is the intensity of the central bright fringe, the intensity at adistance x = 4 × 10−5 m from the central maximum is
