The Energy Dependence of the Photoelectric Attenuation Coefficient of Substances
Introduction: The photoelectric attenuation coefficient of substances is known to depend upon the energy E of the photon and the effective atomic number of substances (Zeff) as (Zeffx/Ey). No definitive values about these indices x, y are given in the literature. The index x is said to lie between, 3.0 and 4.0, while for ‘y’ different values have been assigned, between 3.0 and 4.0. Method...
متن کاملConcerning Hertz’ photoelectric effect
Experimental evidence of the photoelectric effect goes back to H. Hertz. It occurred during the famous confirmation experiments of the Maxwellian theory. It is commonly held however that it cannot be explained in the framework of that theory. We are calling attention to some aspects linked with the interpretation of that effect on which, in our opinion, it is worth-
متن کاملThe Photoelectric Effect: Determination of Planck’s Constant
We test Einstein’s theory of the photoelectric effect, which predicts a linear relation between the energy of light incident on a metal surface and the energy of the emitted electrons. We determine the electron stopping voltage as a function of frequency of incident radiation by illuminating a potassium cathode and constraining the wavelength of incident radiation using several optical band-pas...

cues and they often take precedence over intra-maze stimuli. One possible disadvantage of the present apparatus should be mentioned. A few Ss in the SOW group of each experiment were observed to strenuously oppose box withdrawal throughout training by wedging themselves into the corner between the fixed end wall and the moving floor and side walls. These Ss seldom avoided. Many other Ss display...
