Malta cross tube
With this tube it is possible to prove that cathode rays spread in a straight line.
A Malta cross- like metal screen can be placed to intercept the cathode ray beam, producing a shadow zone on the screen which satisfies the laws of rectilinear propagation. Operation is only guaranteed with the Ruhmkorff’s coil code 5208.
Two connecting leads (5160) and two alligator clips 5062N, 5062R are required. (not supplied)
