Ultraviolet light of wavelengths \( \lambda_{1} \) and \( \lambda_{2} \) when allowed to fall on hydrogen atoms in their ground state is found to liberate electrons with kinetic energy \( 1.8 \mathrm{eV} \) and \( 4.0 \mathrm{eV} \) respectively. Find the value of \( \frac{\lambda_{1}}{\lambda_{2}} \).https://bit.ly/YTAI_PWAP https://www.pw.live
