Explore the fundamentals of light, gratings, and precise wavelength measurements.
This dissertation presents a two-part study that tests the fundamental law of the grating and demonstrates how the coincidence method can build a consistent wavelength system from a single known line. It combines theory with hands-on apparatus work, showing how meticulous setup and careful calibration yield reliable results.
In clear, step-by-step detail, the book explains the experimental method, the role of international standards, and how calibration curves are used to correct readings. It also describes the equipment and procedures involved in measuring spectra, comparing different gratings, and evaluating sources of error. The results illustrate how two gratings can produce consistent wavelength measurements and how a single known line can underpin an entire wavelength framework.
- Learn the practical steps for wavelength measurement using the coincidence method.
- See how calibration curves are created and applied to plate errors.
- Understand the setup, including apparatus, standards, and measurement strategies.
- Review the data and interpretations that verify the fundamental law of gratings.
Ideal for readers of historical and technical studies in optics, this edition stands as a detailed record of early 20th‑century grating work and its methods.
