Light described at a place by the equationE=100[sin(5*10^15)t + sin(8*10^15)t] falls on the metal surface having work function 2eV.calculate the maximum kinetic energy of photoelectrons?Solution) 5x 10^15 and 8x 10^15 are angular frequency of the light. so u can calculate frequency from the anglular freq asw= 2pi v so v = w/2(pi) after that calculate the mean freq by sqaring and adding then take out the sq root .that is ur freqq ... then equate it to einsteins photoelectric eqn .
