The study of the velocity of electrons in the photo-electric effect, as a function of the wave-lengths of the light (1912)
Cornelius, David William, 1883- · leaf 29
od of magnetic deflection is thatit gives an independent determination of the velocity of the elec-trons, so that it would be desirable to be able to use it. After re-peated trials, the magnetic deflection method was given up, since itwas found impossible to measure the photo-electric current.… … Fia. v. or through the vapor of the alkali metal diminishes the final valueof the equilibrium potential. Moreover, the potential measured bythe electrometer is due to the equilibrium potential and partly tocontact electro-motive forces or potential differences of any othernature. All these…
