EMERSON EFFECT LIGHT HAS CHARACTERISTICS OF BOTH A PARTICLE AND A WAVE A WAVE IS CHARACTERIZED BY A WAVELENGTH AND A FREQUENCY c = LIGHT IS ALSO A PARTICLE WHICH WE CALL A PHOTON EACH PHOTON CONTAINS AN AMOUNT OF ENERGY CALLED A QUANTUM. THE ENERGY CONTENT OF LIGHT IS NOT CONTINUOUS, BUT IS DELIVERED IN DISCREET PACKETS OR QUANTA. E = h, where h is Planck’s constant

EMERSON AND ARNOLDS FLASHING LIGHT EXPERIMENTS WITH CHLORELLA
(1932)1. Gave brief flashes (10-5 s) of light to Chlorella
suspension and measured the amount of O2 produced. (The flashes
were spaced 0.1 s apart for maximum efficiency of dark reaction.)2.
Varied intensity (light energy) of flash and plotted the O2
produced per flash versus the flash energy (number of photons).
