NO .. it shows just the opposite. The TOTAL amount of energy is proportional to the number of photons (which is proportional to the time). That can ONLY be the case if each photon has the SAME energy > (because it is delivering its energy to the electrons!!) > AND ELECTRONS IN THAT EFFECT FLOW > IN A CONSTANT STREAM THAT IS LINEARLY > PROPORTIONAL TO ELAPSE OF TIME So proportional to the NUMBER of photons. > it can be measured by an Ampermeter That gives more current when more photons arriving in a given time > while an ampere meter measures the number of electrons passing as > a function of time! It is a current flow .. a rate per unit of time. So with constant light source, you get constant current.

Of course ... noone (other than you) has made any claims about photons being somehow limited to whole seconds. > (ie the same electron intensity flow > during less then a second as well )!!! > right?? And none of that prove you right. Indeed .. it proves you wrong

MR Ben we see in my torch light and photoelectric experiment that if for instance we take a torch that is emitting (th e same intensity of led light) say in (case 1 ) 0.1 second 1 electrons and in (case 2) 0.9 seconds 9 electrons will you say that it was done : in case 1 by a 'small photon' and in case 2 ' 9 times bigger' photon or may be case 2 9 times more photons ??

OK, let's consider a single photon. In special relativity, if a train were travelling at a speed near c , it would shrink in length (maybe only in the direction of travel) to nearly Planck length. That is something special about speed c. A photon travels at speed c and is also, and necessarily, of size not more than one Planck length (maybe only in the direction of travel using this reasoning). A photon is created at the same instant that an electron moves in the atom [but surely not every time an electron moves by a Planck length], and an electron is a point particle ('point' not implying to me absolute zero size but meaning not more than of Planck length). So that condition could imply that a photon is less than a Planck length in size in all directions. Whereas all electrons are identical, not all photons are identical. Even though a photon is contained within a Planck cube size, and is created in an instant, it can have large or small energy. Using special relativity, you could also imagine shrinking a car or train or planet to near quantum size in the direction of travel. Travellling at near speed c shrinks lengths of anything no matter how much energy it contains. Likewise a single photon, travelling st speed c, can be of any amount of energy, depending on the conditions in the atom at the time of its emission (though I don't know much about those conditions). Are you thinking of all quanta being identical, like all electrons are identical? That could explain why you think you need more quanta to build up to a particular observed energy in a beam of light? Whereas a single photon can be as energetic as you like. I am still thinking about whether quanta are truly indivisible after absorption in the atom as it seems rather pre-darwinian by analogy. Ie for all quanta to be created long ago and be immutable seems too constrained? A photon is indivisible during transmission as any attempt to divide it would destroy the photon. But can a photon be a collection of different energies, which are an indivisible aggregate only for so long as it is in the form of a photon. A photon is emitted instantaneously, but the electron (speed < c) must take time to find its new place in the atom. As energy is quantised, how can the electron always and unerringly find a new niche in the atom at just the correct energy level. It is too late to undo the emission, if scrabbling to find a niche, as the photon is long gone. It is a transaction and calculation done at the moment of emission? Or is it not so difficult for an electron to find a niche of any required energy level? Also, the motion of the electron cannot cause the photon to be emitted as the electron must move many Planck lengths to find its new niche in the atom, but only one photon is emitted. Ben
