Suppose a monochromatic X-ray beam of wavelength 100 pm is sent through a Young’s double slit and the interference pattern is observed on a photographic plate placed 40 cm away from the slit. What should be the separation between the slits so that the successive maxima on the screen are separated by a distance of 0.1 mm?
wavelength of mono-chromatic beam
distance of screen from the slit
Distance between successive maxima
formula relating λ, D and β, given by
here, d is the separation between the slits
Distance between separation of each slit
