K.C.S.E Physics Q & A - MODEL 2007PP2QN11&12
The graph in figure 8 shows the variation of photoelectric current with applied voltage when a surface was illuminated with light of a certain frequency. Use the information in the figure to answer questions 11 and 12
On the same axes, sketch the graph when light of higher intensity but same frequency is used to illuminate the surface.
Explain your answer in 11 above
