The hot filament has a myriad of electrons that are constantly undergoing the cycle of energization and de-energization during which it emits photons(light particle) in the infrared region which is commonly known as heat waves.

Why did Crookes cathode ray tube glow green?

The electrons emitted from cathode hit the glass of the tube, causing it to fluoresce.


Can an animal see electrons emitted by a cathode ray tube?

no


How does a hollow-cathode lamp function in analytical chemistry techniques?

A hollow-cathode lamp in analytical chemistry techniques functions by using a cathode made of a hollow tube filled with a specific metal. When a voltage is applied, the metal atoms in the tube are excited and emit light at specific wavelengths. This emitted light is then used for elemental analysis in techniques such as atomic absorption spectroscopy.


Where did the electrons from cathode ray come from?

In a cathode ray tube (CRT), the particles, which are electrons, originate at the heated cathode, becoming the so-called cathode rays. The electrons stream off the cathode and rush over to the anode.


Where does the thermionic emission occur in cathode rays tube?

Thermionic emission occurs at the cathode in a cathode ray tube, which is a vacuum tube that generates electron beams. When the cathode is heated, electrons are emitted and accelerated towards the anode, leading to the generation of cathode rays within the tube.


Is cathrone rays steams of electron?

yes, cathode rays are streams of electrons


What is the positively charged disk called of a cathode?

The positively charged disk in a cathode ray tube is called an anode. It accelerates the electrons emitted by the cathode towards the screen, where they create the visual display.


What is the nature of charge on cathod rays?

Cathode rays are negatively charged particles, which are typically electrons. These electrons are emitted from the cathode in a vacuum tube and are attracted to the positively charged anode.


How were electrons produced from the cathode ray ube?

Electrons were produced in a cathode ray tube by applying a high voltage to the cathode, causing electrons to be emitted through thermionic emission. These electrons were then accelerated towards the anode by the electric field within the tube, creating a beam of electrons known as the cathode ray.


Does a cathode ray tube monitor emit light to form an image?

A: Actually electrons hitting the rare earth deposited on the tube causes photons to be emitted and that is what you see


What did scientist conclude from the fact that when an electrical current passed through a glass tube caused the surface of the tube directly across from the cathode to glow?

Scientists concluded that the glow observed on the surface of the tube opposite the cathode was due to the presence of rays emitted from the cathode. These rays were later identified as electrons, leading to the discovery of cathode rays and the development of cathode ray tubes. This phenomenon provided important insights into the behavior of charged particles in the presence of an electric field.


What following piece of equipment was used by jj Thomson to find electrons?

J.J. Thomson used a cathode ray tube to discover electrons. By passing an electric current through the tube, he observed the deflection of a beam of electrons, which led to his conclusion about the existence of electrons.
