Dual Nature Of Radiation

The electric field at a point associated with a light wave is given by

E = 200 [sin (6 \(\times\) 10¹⁵)t + sin (9 \(\times\) 10¹⁵)t] Vm^\(-\)1

Given : h = 4.14 \(\times\) 10^\(-\)15 eVs

If this light falls on a metal surface having a work function of 2.50 eV, the maximum kinetic energy of the photoelectrons will be
