PHOTOELECTRIC EFFECT AND EINSTEIN (Es) –
RADIATION MEASUREMENT UNIT LIGHT – PART II
Albert Einstein in his honour, in recognition of his scientific contributions and merit, his name has been assigned to a unit of luminous radiation – Einstein (Es) representing the energy of a mole of photons transmitted to an electron and the 99- th element of the periodic table (actinide) was named einsteinium (Es). The main sizes photometers, photon and radiometric showing their name (in Romanian, English and French), the symbol/notation used and the unit of measurement, as well as some conversion factors between certain sizes radiometric, photometric and photonics are presented in tabular form.
Keywords: units of light radiation, Einstein (Es), sizes photometric, radiometric and photonics, conversion factors, tabular presentation
