Q1
A beam of light consisting of two wavelengths, and , 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 .(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 and the screen is at a distance of from the slits.
