Four-Function Calculator Used to Compute Wavelength Automatically
Abstract:An inexpensive four-function calculator is being used to calculate on-line the wavelengths of spectral lines on photographic plates measured with an optical comparator. Although all precise wavelength calculations are made by fitting data to a polynomial equation in a computer program, it is often desirable to know quickly the wavelength of some spectral line or whether there is a line at some known region. An on-line wavelength calculation while the spectrum plate is still on the optical comparator and the spectral line or region is still in view greatly assists the operator.
