SUMMARY
The discussion centers on the relationship between the intensity of monochromatic blue light and the energy of individual photons. It is established that increasing light intensity does not affect the energy of each photon, which is defined by the equation Energy of a photon = hƒ. Instead, higher intensity results in a greater number of photons, leading to an increased number of ejected electrons. The correct graph representing this relationship is identified as graph E, contrary to the answer key's indication of graph C.
