About this title

Synopsis

How light controls electron escape: classic experiments challenge simple ideas about energy and frequency.

In this study, early work on the photo-electric effect is presented through detailed experiments with alkali metals like cesium and potassium. The data, charts, and narrative explain how the maximum potential of emitted electrons relates to the square of light frequency, and how this challenges Planck’s law as it was then understood. The edition emphasizes observed trends, measurement challenges, and the evolving interpretation of light energy in these metal surfaces.

Readers will see how researchers linked measurements of deflection, voltage, and temperature to fundamental questions about energy transfer, work functions, and electron velocity. The material combines practical experiment notes with the theoretical implications of the time, including discussions of the energy balance and the role of surface conditions.

Real data from cesium and potassium cells, with frequency and deflection measurements.
Graphs and discussions showing maximum potential varying with the square of light frequency.
Explanations of how kinetic energy, work to expel an electron, and surface effects come together.
Connections to broader questions in early quantum theory and Planck’s law.

Ideal for readers of the history of quantum physics and anyone curious about how early experiments shaped modern ideas of light and matter.
