DESCRIPTION
Hook line: Learn how scientists measure light and heat to understand how lamps and flames perform. See practical methods scientists use to map energy in the visible and invisible spectra.
In these pages, readers explore how energy from light sources is measured and analyzed. The text explains different instruments, like thermopiles and radiomicrometers, and describes how to correct for absorption, dispersion, and other factors. It’s a practical, experiment-focused look at quantifying light energy and its efficiency in real-world sources.
- How energy curves are built by plotting light energy against wavelength.
- Definitions of radiant and luminous efficiency and why they matter for lighting design.
- Practical notes on instrument use, calibration, and key corrections.
- Comparisons of methods for separating light from heat in experiments.
Ideal for readers of scientific instrumentation and early 20th‑century radiometry, this edition offers concrete methods and context for studying light production.
