to put an end to this speculation the PHOTO ELECTRIC EFFECT WAS
DISCOVERED BY HERTZ IN 1887 IT WAS FOUND SPARKS FORMED MORE EASILY
BETWEEN A BRIGHTLY ILLUMINATED SPARK GAPS METAL ELECTRODES...ALL METALS
HAVE A WORK FUNCTION DEFINED BY HF=E(ESCAPE)+1/2MVSQUARED,ORDINARY BLUE
LIGHT CAN PROVIDE 3 ELECTRON VOLTS PER ENCOUNTER WHICH IS SUFFICENT FOR
ELECTRON EMMISIONS FROM ALKALI METALS REF.P.686 PHENOMENAL PHYSICS
SWARTZ .....LENARD STUDIED IT IN 1900 USING VACUUM TUBE
TECHNOLOGY....THATS ALL TESLA WAS DOING BY HIS RADIANT PHOTO ELECTRON
PLATE AND HIS VACUUM PHOTO ELECTRON TUBES DEVELOPED BY LENARD......NOW
FOR THE CURIOUS ABOUT REVERSE PHOTO ELECTRON OR THERMAL ELECTRON EFFECT
TAKE A 4 FOOT FLOURESCENT LIGHT BULB AND SLOWLY PULL A GAUNTLET OF
ALUMINUM FOIL DOWN ITS LENGTH IN A DRY DARK ROOM THIS WILL LIGHT THE
BULB BUT IT WILL ALSO PULL OFF BY STATIC ELECTRIC ATTRACTION ELECTRONS
CAUSING THE FOIL GAUNTLET TO BECOME NOTICABLY COLDER DO IN PART TO THE
ALUMINUMS WORK FUNCTION AS THE ELECTRONS GAIN ENOUGH ENERGY IN THE
ELECTROSTATIC FIELD TO BE PULLED AWAY THERE MAY BE OTHER EXPLANATIONS
I.E. ION COOLING BUT THE FOIL DOES GET COLDER THE MORE THE TUBE GLOWS
AND ELECTRIFYS.A NICE LONG STEADY PULL WORKS BEST ....
