A beam of light consisting of two wavelength `650nm` and `520nm` is used to illuminate the slit of a Young's double slit experiment. Then the order of the bright firnge of the longer wavelength that coincide with a bright fringe of the shorter wavelength at the least distance from the central maximum is

A beam of light consisting of two wavelengths, 650 nm and 520 nm, is used to obtain interference fringes in a Young's double-slit experiment. (a) Find the distance of the third bright fringe on the screen from the central maximum for wavelength 650 nm. (b) What is the least distance from the central maximum where the bright fringes due to both the wavelengths coincide?The distance between the two slits is 0.28mm and the screen is at a distance of 1.4m from the slits
