question

(a) can the interference pattern be produced by two independent monochromatic sources of light? explain.

(b) the intensity at the central maximum (o) in a young’s double slit experimental set-up shown in the figure is . if the distance op equals one-third of the fringe width of the pattern, show that the intensity at point p, would equal .

c) in young’s double-slit experiment, the slits are separated by 0·5 mm and the screen is placed 1·0 m away from the slit. it is found that the 5th bright fringe is at a distance of 4·13 mm from the 2nd 'dark fringe. find the wavelength of light used.
