This chapter provides an overview of blackbody radiation. All objects that have a temperature at any value other than absolute zero continuously emit and absorb radiation. The radiation characteristics of certain surfaces are completely specified if the temperature is known. These surfaces radiate continuously through the optical spectrum and are known as ideal thermal radiators or blackbodies. Blackbody radiation is described by Planck's equation. Slide rules are available that provide rapid calculation of blackbody quantities with good accuracy. The Planck radiation formula shows that the spectrum of the radiation shifts toward shorter wavelengths as the temperature of the radiator is increased. The derivative of the Planck equation with respect to wavelength yields the Wien displacement law that gives the wavelength for which maximum radiation occurs for a given temperature. The total power radiated per unit area of a blackbody is obtained by integrating the Planck's radiation law over all wavelengths. Two well-known approximations to Planck's law are readily obtained: Rayleigh-Jeans' law and Wien's radiation law. The chapter also highlights emissivity, Kirchhoff's law, and Lambert's cosine law. Emissivity of a surface is a function of wavelength, temperature, and direction. Lambert's cosine law signifies that the amount of energy in a given solid angle varies in proportion to the cosine of the angle between the direction in question and the normal to the surface.

Bulletin of the Bureau of Standards [voi.n even less is sometimes desired.The former requires resistance measurements with an accuracy of about i in 300 000, while the latter, involving the measurement of a small change in a large quantity, requires a precision in each measurement of the order of 1 part in 3 000 000 or more.In nearly all cases in which such measurements have been made the electrical apparatus has been of special design. MERCURY LINKS AND SHUNT DIALSTo attain the above accuracy in measurements of resistances of the magnitudes usual in resistance thermometry (1 ohm to 100 ohms) , the errors due to contact resistances of plugs, switches, etc., must be minimized.One familiar method of doing this is by use of mercury-cup contacts for links connecting the parts of the circuit.This is fairly satisfactory for the larger valued decades of a Wheatstone bridge, but is impracticable for several reasons in the decades comprising small fractions of an ohm.An excellent device for these which fulfills the requirement of greatly dimin- ishing the effect of dial contact resistances is constructed on the well-known principle of changing the resistance of a circuit by shunting a small resistance with a much larger variable one. 1 The contact resistance of the switch is here a part of the shunting branch, and only a small fraction of its total variation enters into the final result.3.
