357713 Surface of certain metal is first illuminated with light of wavelength \({\lambda _1} = 350\;nm\) and then, by light of wavelength \({\lambda _2} = 540\;nm\). It is found that the maximum speed of the photo electrons in the two cases differ by a factor of 2 . The work function of the metal (in \(eV\) ) is close to \(\left(\right.\) Energy of photon \(\left. { = \frac{{1240}}{{\lambda (in\,nm)}}eV} \right)\)
