Question

Write characteristics of Carhode rays​

Answer 1

They are produced by the negative electrode, or cathode, in an evacuated tube, and travel towards the anode.

They travel in straight lines and cast sharp shadows.

Answer 2

Answer:

Characteristics of Cathode Rays :

1. The cathode rays moves from cathode to amode.
2. These rays are observed with the help of fluorescent or phosphorescent material as these are not visible.
3. These rays travel in straight line in the absence of electric and magnetic field. It is confirmed by the formation of a shadow on the opposite side of the cathode, when a small object is placed between the cathode and anode.
4. They rotate the little paddle wheel placed in their path. This shows that cathode rays contains material particles having both mass and velocity.
5. These rays consists of electrons produced by the ionization of the gaseous atoms by the discharge and they were responsible for the flow of current.
6. The application of electric and magnetic fields deflected cathode rays as expected from negatively charged particles.
7. They produce X-ray when they strike against the surface of hard metals like tungsten, molybdenum, etc.
