TH EMOMENT IT IS DIVIDED BY c it isnot anymore an energy formula but MOMENTUM FORMULA and it makes a principaldifference as you will see later because momentum is not energy !!) so sorry my typo mistake it is not not hf/Lambda but h/lambda or hf/lambda (momentum !!!) (i respond quickly and have in my mind just the main arguments so such mistakes can occure in my **quick responds ** ***unlike** my main analysts in which i spend more time checking it !! and i noticed it before anyone to correct me (:-)) so please MR PD ---as above just give us *your analysis **of it TIA Y.Porat --------------------

Do you understand it?

Do you understand it? ------------ psychopath crook with 3 different anonymous names DO YOU THINK THAT PD NEEDS YOUR FUCKEN crooked HELP?!! 2 NASTY PIGGY YOU 'FORGOT'' THE DIMENSION LESS FIGURES !!! (not accidentally (:-) so little Josef Goebbels jut let PD do it ** properly and honestly ** and completely to the last detail !! !! 'THE DEVIL IS IN THE DETAILS' !!!) TIA to PD Y.Porat -------------------------------

Yes .. you most certainly do > 2 > NASTY PIGGY > YOU 'FORGOT'' THE DIMENSION LESS > FIGURES !!! (not accidentally (:-) No .. I didn't FORGET them .. and it wasn't accidentally .. you asked for a DIMENSIONAL ANALYSIS which does NOT include the dimensioless values .. only the dimensions. THAT is why it is called DIMENSIONAL analysis. Get it? Probably not. > so little Josef Goebbels Not me > jut let PD do it ** properly and honestly ** No need ..

Complete and detailed. > 'THE DEVIL IS IN THE DETAILS' !!!) Yes it is .. you seem to ignore details like: what is a dimensional analysis. > TIA to PD Note that even including a dimensionless number (so its no longer dimensional anlysis) does not change anything .. the value is arbitrary (depending on the units you use and the values of the variables involved). All you'll end up showing is what we already know .. photon momentum is proportional to frequency and inversely proportional to wavelength (with some unit-dependent ratio).
