मयाधान: \( \mathrm{E}=\frac{\mathrm{hc}}{\lambda}=\frac{6.63 \times 10^{-34} \times 3 \times 10^{6}}{3000 \times 10^{-10}} \mathrm{~J}=6.63 \times 10^{-19} \mathrm{~J}=4.14 \mathrm{eV} \) \[ \mathrm{E}_{\mathrm{k}}=\mathrm{E}-\phi=(4.14-2.3) \mathrm{eV}=1.84 \mathrm{eV} \] 02. UV radiation having a 300 mm wavelength falls on uranium metal, ejecting 0.5 cV electrons. What is the binding energy of electrons to uranium metal? (Planck's constant \( =6.63 \times 10^{-34} \mathrm{kgm}^{2} \mathrm{~s}^{-1} \) )
