In Young’s double slit experiment, fringes of width β are produced on the screen kept at a distance of 1m from the slit. When the screen is moved away by 5×10^−2 m, fringe width changes by 3×10^−5 m. The separation between the slits is 1×10^−3 m. The wavelength of light used is nm. fringe width [...]
