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. ...
