An Interferometer Method of Determining Wavelengths in the H-D Spectrum (Classic Reprint) - Softcover

Inhaltsangabe

Explore how scientists measure light with precision using an interferometer. This nonfi ction work explains a method for determining wavelengths in the hydrogen–deuterium spectrum, using careful standards and an optical setup that combines a Fabry-Perot interferometer with a plane grating.

Two parts document the practical steps, from setting up the apparatus to calculating wavelengths. The author compares hydrogen, iron, and deuterium lines, and discusses how temperature, plate separation, and accurate standard references affect results.

- Learn how to measure spectral lines with an interferometer
- See how standards are chosen and verified for accurate wavelength values
- Understand the practical challenges of long exposures and temperature effects
- Follow the step-by-step approach to deriving precise wavelengths from observed patterns

Ideal for readers of historical scientific methods, spectroscopy, and precision measurement, this edition offers a clear view of experimental design and data analysis in early interferometer work.
