Cathode-ray tube with metal screen
Cathode-ray tube with a metal screen for demonstrating that cathode rays travel in straight lines and cast a shadow behind the screen.
Demonstration device on the topic “Electric current in a vacuum”: a glass vacuum flask with a cathode, anode and a metal shutter-screen on a stand. Designed for 3 demonstrations: rectilinear propagation of cathode rays in a vacuum, shielding of the rays by a metal barrier with the formation of a shadow that follows the shape of the shutter, and luminescent glow of glass under the influence of the rays. A classic experiment for studying the nature of an electron beam.
