RECTILINEAR PROPAGATION
V shaped tube, To show cathode rays are generated only vertical (lower electrode) irrespective of the anode point, (any of two electrodes above). |
|
|
|
|
|
REPILSION TUBE GOLD STEEN'S
Vertical tube with two parallel wire cathodes at two end of tubes with third electrode to serve as anode on base. |
|
|
|
|
|
MECHANICAL EFFECT
Cathode Rays exert a pushing effect on objects it falls on, is shown by the rotating vanes by the force extended by cathode rays. |
|
|
|
|
|
MAGNETIC EFFECT DEFLECTION
Running cathode rays are visible to naked eye by the glowing path on fluorescent screen. When a magnet is brought near, the deflecting path cathode rays is vividly visible. Supplied without magnet. |
|
|
|
|
|
SHADOW EFFECT MALTESE CROSS
Upon focussing at a point, cathode rays generate intense heat shown by the red heating of platinum foil. |
|
|
|
|
|
|
HEATING EFFECT PLATINUM FOIL
When cathode rays are focussed on wax coated on the outside of the upper round head of cathode ray tube, the wax melts quickly showing heat generated by cathode rays. |
|
|
|
|
|
HEATING EFFECT WAX COATING
Vertical tube with two parallel wire cathodes at two end of tubes with third electrode to serve as anode on base. |
