In a photoelectric effect experiment, the threshold wavelength of light is$380\mathrm{ }\mathrm{n}\mathrm{m}$. If the wavelength of incident light is$260\mathrm{ }\mathrm{n}\mathrm{m}$, the maximum kinetic energy of emitted electrons will be
Given$\mathrm{E}$(in$\mathrm{e}\mathrm{V}$)$=\frac{1237}{\mathrm{\lambda }\left(\mathrm{i}\mathrm{n}\mathrm{ }\mathrm{n}\mathrm{m}\right)}$
