Three different types of Cathode Ray Tubes each comprising a horizontal glass tube fitted with an aluminium plate coated with fluorescent material.
Cathode rays pass through the slit on the cathode end bent at right angles casting a sharp, bright image across the aluminium plate then deflect when a magnet nears the tube. * A POWER SUPPLY IS REQUIRED FOR ALL APPARATUS – Refer to HIGH VOLTAGE SOURCE KIT listing *.
