A series of discoveries and proposed models led to Einstein’s explanation of the photoelectric effect. The sequence below shows some of these significant events.       Light is described as a wave.                                mc004-1.jpg Hertz determines that light shining on metal produces emissions.                 mc004-2.jpg The particles emitted are identified as electrons.                     mc004-3.jpg _________________________________   Which event should be added to the end of this sequence?
