Properties of cathode ray and it's explanations
Answers
♣They travel in straight lines and cast sharp shadows.
♣ They have energy and can do work.
♣ They are deflected by electric and magnetic fields and have a negative charge.
♣They are beams of tiny, negatively charged particles called electrons.
Answer:
the electrons are being emitted from the negative charged element in the vacuum tube called the cathode
Explanation:
They travel linearly
They have a negative electric charge
They have particle property
Magnets can deflect them
Charge/mass ratio of the rays is constant
They travel from the cathode to the anode
Their properties are independent from the electrodes and gas present in the cathode ray tube.
Cathode rays can ionize gas
The travel more slowly than light
They can heat objects that they hit
They can penetrate through thin Aluminium plates
They can make phosphors glow
