A metallic surface is illuminated alternatively with light wavelengths 3000 0A and 6000 0A. It is observed
that the maximum speeds of the photoelectrons under these illuminations are in the ratio 3 :1. Calculate the
work function of the metal and the maximum speed of the photoelectrons in two cases.
