Webequations. Einstein and Millikan described the photoelectric effect using a formula (in contemporary notation) that relates the maximum kinetic energy ( Kmax) of the photoelectrons to the frequency of the absorbed photons ( f) and the threshold frequency ( f0) of the photoemissive surface. Kmax = h ( f − f0) WebAs the intensity of incident light increases the photoelectric current produced also increases. So the correct answer is option (A.)

Webis determined by measuring the electric current; is directly proportional to the intensity of the incident light when frequency is constant; On a graph of maximum kinetic energy vs. frequency… all curves are linear with slope equal to Planck's constant. h = 6.63 × 10 −34 J s. WebClassical solution to photoelectric effect If light is a classical wave, one predicts that it just puts energy into plate, heats up, get diode current voltage curve. 0 Voltage Also takes time to heat up. • Light on longer, heat more, more electrons and electrons have higher KE. • Color light does not matter, only intensity. WebThe effect of changing incident frequency v can also be studied from the plot of photoelectric current Vs potential applied across CD, keeping the intensity of incident radiation same. From graph, we see that i max is same in all cases (for same intensity). From graph, as v increases, V c becomes more negative. how child abuse influence enviroment
