WebThe IF function allows you to make a logical comparison between a value and what you expect by testing for a condition and returning a result if that condition is True or False. … WebIn first case, eV s1= λ 1hc−W .... (1) where W= work function of metal surface. Since work function does not depend on wavelength of incident light so it will be constant for both cases. Thus, W= λ 2hc−eV s1 or W= 550×10 −9(6.62×10 −34)(3×10 8)−(1.6×10 −19)(0.19)=3.31×10 −19J=2.07eV Since 1eV=1.6×10 −19J Was this answer helpful? 0 0
