    The magnetic field associated with a light wave is given at the origin by \[B={{B}_{0}}[sin(3.14\times {{10}^{7}})ct+sin(6.28\times {{10}^{-7}})ct].\] If this light falls on a silver plate having a work function of 4.7 eV, what will be the maximum kinetic energy (in eV) of the photoelectrons? \[(c=3\times {{10}^{8}}m{{s}^{-1}},h=6.6\times {{10}^{-34}}J-s)\]

    Answer:

    7.7
