Final answer:
The pattern of electrons emitted from a cathode in an image-intensifier tube is regular, due to the wave-like behavior and self-interference of electrons. Historical cathode ray tube experiments have shown that electrons have mass and carry momentum, and their paths can be bent by magnetic fields.
Step-by-step explanation:
The behavior of electrons emitted from the large cathode end of an image-intensifier tube deals with how these particles form an interference pattern as they fall on a detector. This pattern is not random, circular, or spiral but is regular due to the wave-like properties of electrons, leading to a phenomenon known as self-interference, where particles interfere with themselves. This implies that each electron has a probability distribution that covers multiple paths, contributing to the buildup of a regular interference pattern.
Historical experiments involving cathode ray tubes, such as the one where a paddle wheel was rotated towards the anode, demonstrated that electrons indeed have mass and are able to carry momentum. The path of these electrons can be affected by magnetic fields, illustrating their charge properties. Considering these characteristics and patterns of electron behavior, we can learn about the fundamental properties of electrons and their interactions with other particles and fields.
