1. The problem statement, all variables and given/known data What is the maximum number of electrons that can be freed by a burst of light whose total energy is 1.16 µJ? 2. Relevant equations E=hv v=c/[tex]\lambda[/tex] 3. The attempt at a solution I have no problem calculating frequencies and wavelengths, my issue is how can I use these numbers to relate to number of electrons emitted. Our book tells us that light with a frequency of 4.60X10^14 s^-1 or greater will cause cesium metal to emit electrons...the above frequency comes out to 1.75X10^27 meaning it will emit electrons....what I need is some equation that relates electron emission to any of the aforementioned quantities I can find.
