Wave-Particle Duality of Light. click here to see a wave experiment . ... In the wave theory, greater light intensity simply means more photons. Each photon ejects electrons in the same way, so more intensity means more electrons. Threshold frequency and electron K.E. should not be affected by intensity. ... Light frequencies below the threshold eject no electrons, no matter how intense the light. Light frequencies above the threshold eject electrons, no matter how low the intensity. ...

Imagine that you are doing particle physics experiments. You fire a beam of sub-atomic particles of mass 4.0x10 -24 kg into your detector at a speed of 100 m/s. Most pass straight through undeflected, but one of them came out with its mass reduced to 3.0x10 -24 kg, its speed reduced to 80 m/s, and in a direction which was deflected by 2.4 degrees from its original path. You think that it must have ejected a particle of mass 1.0x10 -24 kg. ...
