\lambda_{1} and \lambda_{2} are used to illuminate the slits. \beta_{1} and \beta_{2} are the corresponding fringe widths. The wavelength \lambda_{1} can produce photoelectric effect when incident on a metal. But the wavelength \lambda_{2} cannot produce photoelectric effect. The correct relation between \beta_{1} and \beta_{2} is

λ1 and λ2 are used to illuminate the slits. β1 and β2 are the corresponding fringe widths. The wavelength λ1 can produce photoelectric effect when incident on a metal. But the wavelength λ2 cannot produce photoelectric effect. The correct relation between β1 and β2 is

β1<β2
β1=β2
β1>β2
β1≥β2
