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.
When did Cathode ray tube amusement device happen?
Cathode ray tube amusement device happened in 1947.
Why the cathode in cathode ray tube is indirectly heated by the filament?
To create an electron cloud that can be shaped into a beam.
In a cathode ray tube where do the particles originate towards what Do they move?
The particles originate from the Cathode in the neck of the tube. They are liberated by a heater. The electrons thus liberated are attracted by the Anode, by applying a high voltage to it. In a CRT there are several anodes, the largest and biggest is formed by a coating inside the tube towards the screen. This attracts and accelerates the electrons in a stream of particles known as a 'cathode ray'. They carry on in a straight line, once accelerated, until they hit the screen and cause a phosphor coating to glow, on the inside surface of the screen. The cathode ray can be bent from it's course, by using electromagnets arranged around the neck of the tube.
Why is it necessary to decrease pressure in the discharge tube to get cathod rays?
why it is necessary to decrease the pressure in the discharge tubbe to get cathode rays
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
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.
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 following piece of equipment was used by jj Thomson to find electrons?
JJ Thomson discovered electrons using a cathode ray tube.
What did jj thomas discover?
J.J.Thomas discovered that atoms have negatively charged particles called electrons. He discovered this using the Cathode Ray. The cathode ray is a beam of electrons emitted by the cathode of an electrical discharged tube.
What is the function of cro?
CRO consists of a cathode ray tube which is having the vacuum conditions . The electron beam is emitted by a cathode at the rear end of the tube. This beam is accelerated and focused by one or more anodes. The rays then strike the front (other end) of the tube and produces a bright spot on the phosphorescent screen
What is the negatively charged electrode of a cathode ray tube?
The negatively charged electrode of a cathode ray tube (CRT) is the cathode. The tube is a cathode ray tube, and electrons stream off the cathode, are accelerated across the evacuated space and "directed" either electromagnetically or electrostatically, and then strike the phosphor coating on the positively charged anode at a "location" determined by the "directing" elements.
What is the full meaning of CRT in computer?
A "CRT" is a cathode ray tube. An old style computer monitor (not computer).
Why television are also known as cathode ray tube?
because cathode ray tube is the heart of the television.
Who first invented the cathode ray tube?
The cathode ray tube was invented in 1897 by Ferdinand Braun.
Is cathode ray tube and electron tube same?
Yes they are the same. A cathode ray tube (CRT) uses an electron gun to "shoot" electrons from the cathode to specific positions on the anode of the CRT.
