The following paradox is discussed. According to Bohr's theory the frequencies of light emitted by hydrogen are given by: f=(2 pi 2me4/h3)((1/N2)-1/n2)), m is mass of electron, e its charge, h is Planck's constant, N and n are integers, and f is freq

Forced vibration of strings

Autor: H. L. Armstrong

Publikováno v: American Journal of Physics. 50:1028-1031

The forced vibration of strings has much in common with, on the one hand, their free vibration and, on the other hand, the forced harmonic motion of single objects. But there are also peculiarities, some of which are investigated here. It is found us

Reverse Characteristics of High Inverse Voltage Point Contact Germanium Rectifiers

Autor: J. H. Simpson, H. L. Armstrong

Publikováno v: Journal of Applied Physics. 24:25-34

A theory of the reverse characteristic of high inverse voltage germanium rectifiers is developed, which takes account of the radial symmetry of the point contact and the presence of positive holes in the ``inversion region'' of the semiconductor. The

On a Space-Time Representation of Nonrelativistic Wave Mechanics

Autor: H. L. Armstrong

Publikováno v: American Journal of Physics. 25:195-199

A space-time representation is developed for nonrelativistic wave mechanics as was done for classical mechanics, by adding to the system a rotating body to serve as a clock, and applying the time-independent forms of the equations of motion. The usua

On Avalanche Multiplication in Semiconductor Devices†

Autor: H. L. Armstrong

Publikováno v: Journal of Electronics and Control. 5:97-104

Recently, evidence has been presented to show that the ionization coefficients for holes and electrons in semiconductors have much the same form as functions of field strength, as do the ionization coefficients in a gas discharge. On this basis, the

The Dielectric Constant of Dry Air

Autor: H. L. Armstrong, J. V. Hughes

Publikováno v: Journal of Applied Physics. 23:501-504

A sensitive and accurate method for determining the real part of the dielectric constant of gases at microwave frequencies is described. The method eliminates some possible sources of systematic error inherent in earlier methods.The dielectric consta

The Weight of Mass

Autor: H. L. Armstrong

Publikováno v: American Journal of Physics. 33:832-835

It is argued that insistence on the use of the word “mass,” where one would ordinarily say “weight” is nothing but pedantry, and imposes a needless “weight,” i.e., burden, on students. Evidence is invoked from laws that the word “weight
