Q4
In Young's double slit experiment, fringes of certain width are produced on the screen kept at a certain distance from the slits. When the screen is moved away from the slits by 0.1m, fringe width increase by 6×105m. The separation between the slits is 1 mm. Calculate the wavelength of the light used.
