What is Crookes about?
The document discusses the discovery of electrons through the study of cathode rays by William Crookes in 1879. It details the experimental setup using Crookes tubes and the observations made at various gas pressures, leading to the conclusion that cathode rays are negatively charged particles called electrons. Key properties of cathode rays include their ability to rotate a paddle wheel, deflection in electric and magnetic fields, heating effect on metal foils, and ionization of gases.
