For photoelectric effect,(i) KE=E−E0​where,KE= Kinetic energy of ejected electrons.E= Energy of incident light =hvE0​= Threshold energy =hv0​v= Frequency of incident lightv0​= Threshold frequencySlope =±1, intercept =−E0​So, option (a) is correct.(ii) KE of ejected electrons does not depend on the intensity of incident light
So, option (b) is correct.
(iii) When, number of ejected electrons is plotted with frequency of light, we getSo, option (c) is also correct.(iv) KE=hv−hv0​Slope =+h, intercept =−hv0​So, option (d) is not correct.
