In Young's double slit experiment carried out with light of wavelength (2) = 5000, the distance between the slits is 0.2 mm and the screen is at 200 cm from the slits. The central maximum is at x = 0. The third maximum (taking the central maximum as zeroth will be at x equal to maximum) (a) 1.67 cm (c) 0.5 cm (b) 1.5 cm (d) 5.0 cm
