Question

How can be show the mechanical effect of cathode rays.​

Answer 1

Answer:

Cathode rays are invisible, but their presence was first detected in early vacuum tubes when they struck the glass wall of the tube, exciting the atoms of the glass and causing them to emit light—a glow called fluorescence.

Answer 2

It can be shown by placing paddle wheel between electrodes.

• Because cathode rays can rotate the disc in their path, they exert a mechanical effect.
• In the specific event where a wheel is strategically positioned in the direct line of cathode rays on the bladder of the paddle wheel, it naturally begins spinning.
• Negatively charged elements make up cathode rays. The direct rays are then redirected towards the positively charged plate when they are typically exposed to an electrical field.
