Feature
●★ The Cathod Ray tube comes with a 110v POWER SUPPLY
●★ 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.
●★ 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 (i.e., electron flow).
●★ Straight-in cathode ray tube : Demonstrate the phenomenon that the cathode ray moves in a straight line and can be blocked by metal.
