Question

Write the properties of cathode rays.

Answer 1

• Cathode rays possess energy and momentum and travel in a straight line with high speed of the order of 10⁷ m s^-1
• It can be deflected by application of electric and magnetic fields.
• When the cathode rays are allowed” to fall on matter, they produce heat.
• They affect the photographic plates and also produce fluorescence when they fall on certain crystals and minerals.
• When the cathode rays fall on a material of high atomic weight, x-rays are produced.
• Cathode rays ionize the gas through which they pass.
• The speed of cathode rays is up to (\(\frac{1}{10}\))^th
