there is a potential diff btw d metal that ejects d electrons and d detection device, such dat d detector is at a lower potential than d metal. d electrons slow down as they go 4rm higher 2 lower electric potential; since they must overcome a potential diff 2 reach d detector. 2 reach d detector, the initial k.E of an ejected electron must be greater than or = d amt of energy it will lose by moving thru d potential diff. 4 d incident light to cause the ejection of an electron, the light must impart a certain amt of energy to the electron to overcome the forces that constrain it within d metal. . Diff metals will have diff values for phi. 4 an electron to reach the detector, the light must impart enough energy for the electron 2 overcome both the function & d stopping potential. suppose dat d light carries energy E_light. what is d max stopping potential dat can b applied while allowing electrons to reach the detector?
Express your answer in terms e, E_light, and phi.
