angstrom's Usage Examples:

Angstrom endeavoured to find the variation of conductivity by this method, but he assumed c to be the same for two different bars, and made no allowance for its variation with temperature.

Angstrom's Method consists in observing the propagation of heat waves in a bar, and is probably the most accurate method for 4 4 thehi 's ' 'so ' d 60 measuring the diffusivity of a metal, since the conditions may be widely varied and the correction for external loss of heat can be made comparatively small.

The values obtained in this way for waves having a period of one second and a wave-length of half an inch agreed very well with those obtained in the same cast-iron by Angstrom's method (see below), with waves having a period of i hour and a length of 30 in.

„ k=0.0177 „ Angstrom.

Angstrom's method described below.

Perot's number is now definitely adopted to define the Angstrom, and need never be altered, for should at some future time further researches reveal a minute error, it will be only necessary to change slightly the temperature or pressure of the air in which the wave-length is measured.

The most convenient unit is that adopted by the International Union of Solar Research and is called an Angstrom (A); and is equal to i 08 cms. A.

His son, Knut Johan Angstrom, was born at Upsala on the 12th of January 1857, and studied at the university of that town from 1877 to 1884.

ANDERS JONAS ANGSTROM (1814-1874), Swedish physicist, was born on the 13th of August 1814 at LOgdO, Medelpad, Sweden.

Angstrom in his celebrated researches upon wave-lengths.

angstrom's Meaning':

a metric unit of length equal to one ten billionth of a meter (or 0.0001 micron
