Question

Which of the following is false regarding cathode rays (i.e. beam of electrons


They produce heating effect.
They don't deflect in electric field.
They cast shadow.
They produce fluorescence.​

Answer 1

Explanation:

The stream of electrons in cathode ray tube constitutes the cathode rays. Electrons are emitted by hot filament by the process of thermionic emission.

They are not produced by the cathode ray tube.

Answer 2

b) is the correct option, they don't deflect in an electric field.

What is a Cathode ray and why they don't deflect in an electric field is false?

• Cathode rays are streams that are emitted to negative electrodes.
• The cathode rays display each particle in addition to wave nature.
• Thus it casts a shadow, produces heat effects, and produces fluorescence as well.
• Cathode rays encompass electrons that get deflected withinside the electric-powered field, as a result, cathode rays get deflected withinside the electric-powered field.
