Answer 1

Answer:

73. In a young's double slit experiment, the

separation between the slits =2.0 mm, the

wavelength of the light =600 nm and the

distance of the screen from the slits =2.0 m. If

the intensity at the centre of the central

maximum is 0.20 Wm?, then the intensity at a

point 0.5 cm away from this centre along the

width of the fringe will be
