Cathode Ray Tube Experiments
- A metal plate, shaped like a Maltese cross, was placed near the anode before the fluorescent screen.
- When turned on, it was found that, the cross had blocked the Cathode Rays, and formed a shadow on the fluorescent screen..
- This meant the Cathode Rays had relatively low penetrating power.
- The shadow formed was a cross with very clear edges.
- This meant that the Cathode Rays traveled in straight lines
- This also meant that no diffraction was occuring, and thus the Cathode Ray was likely to be a particle.
- An extremely light, glass paddlewheel was placed within the tube along a set of runners.
- When the tube was turned on, it was found that the paddlewheel spun, and moved towards the anode.
- This strongly suggests that the cathode rays had momentum, and thus mass, another property of a particle.
- It moving towards the anode also suggested the the ray came from the Cathode.
- This is just a standard cathode ray tube shown here.
- When the beam was turned on, it caused the fluorescent screen to light up as a result.
- This meant the Cathode Rays had enough energy to produce the luminescent reaction.
- A magnetic field was passed through a Cathode Ray Tube through the use of a magnet.
- When turned on, the Cathode ray deflected
