Demonstrate environmental conditions The relative humidity is not more than 80%. Temperature -101.—40 degC. Structure Directly enter the magnetic effect The cathode ray tube is composed of a bulb, a baffle plate, a fluorescent plate, a cathode, an anode, a bakelite seat and the like.
Features
- ^LYILIN Straight-in cathode ray tube: Demonstrate the phenomenon that the cathode ray moves in a straight line and can be blocked by metal.
- ^Electrostatic effect cathode ray tube: Demonstrates the phenomenon that the cathode ray deflects in the electric field, which proves that the cathode ray is a negatively charged particle stream (ie, electron flow).
- ^Magnetic field effect cathode ray tube: Demonstrates the phenomenon that the ray is deflected in the magnetic field, indicating that the cathode ray is a charged particle stream emitted from the cathode.
- ^Mechanical effect polar ray tube: Demonstrates the phenomenon that the cathode ray causes mechanical motion of the object, indicating that the cathode ray has momentum and energy.
- ^Scope of application: Teachers teach in laboratory classrooms to increase students’ interest in physics and electricity
