Light of two different frequencies whose photons
\( \mathrm{P} \)
have energies \( 1 \mathrm{eV} \) and \( 2.5 \mathrm{eV} \) respectively,
W
successively illuminate a metal of work function \( 0.5 \mathrm{eV} \). The ratio of maximum kinetic energy of the emitted electron will be \( 1: n \). The value of \( n \) is....
