283342 In Young's double slit experiment, slits are separated by $2\mathrm{mm}$ and the screen is placed at a distance of $1.2\mathrm{m}$ from the slits. Light consisting of two wavelengths $6500\text{AA}$ and $5200\text{AA}$ are used to obtain interference fringes. Then, the separation between the fourth bright fringes of two different patterns produced by the two wavelengths is:

283343 In Young's double slit experiment, two wavelength ${\lambda }_1=780\mathrm{nm}$ and ${\lambda }_2=520\mathrm{nm}$ are used to obtain interference fringes.
