Then identify which of the following metals could be used in such a capacity The maximum value is: Number The following metals could be used in the photovoltaic cell described above (mark all that could be used) silver (0-7.59x10-19 J) silicon (0-7.24x10 tungsten (0-7.20 x 10-19 J) titanium (0-6.94x10-19 J) D barium (D-4298 10- J) potassium (D-3 .78x10-19 J) Hint Check AnswerView Solution Progress:Explanation / Answer
E = h*(C/v)
E = (6.626*10^-34 * 3*10^8)/500*10^-9
E = 3.9756*10^-19 J.
