Summary
The test of Einstein's photoelectric equation which I have considered and save in the case of the last, subjected to accurate experimental verification are: 1. The existence of a definite and exactly determinable maximum energy of emission of corpuscules under the influence of a given wavelength. 2. The existence of a linear relationship between photo-potential and the frequency of the incident light. 3. The exact appearance of Planck's h in the slope of the potential-frequency
line. The photoelectric method is one of the most accurate available methods for fixing this constant. 4. The agreement of the long wave-length limit with the intercept of the P.D., line, when the latter has been displaced by the amount of the contact E.M.F. 5. Contact E.M.F.'s are accurately given by h/ e(0 - 0') - (V0 - V0'). .
