Question

properties of cathode rays​

Answer 1

$\large\bold\purple{Heya\:Mate\:!!}$

1. They travel in straight lines.

2. They are made up of material particles.

3. They carry negative charge.

4. They produce X rays when the strike against the surface of hard metals like tungsten molybdenum.

Answer 2

$\large{\underline{\underline{\sf{Properties\:of\:cathode\:rays-}}}}$

• Cathode rays consists of material particles.

• When electric field is appled to a stream of cathode rays, they get deflected towards positive plate. It shows that cathode rays are negatively charged themselves.

• when magnetic field is applied perpendicular to the path of cathode rays, they get deflected in the direction expected for negative particles. It confirmed that cathodes rays are negatively charged.

• Cathode rays produce x - rays when are made to fall on metals such as tungsten, copper etc.

• Cathode rays travel in a straight line. An object placed in the path of cathode rays casts a sharp shadow. It shows that cathode rays travel in straight lines.
