What else can I help you with?
Is cathrone rays steams of electron?
yes, cathode rays are streams of electrons
How do scientists detect cathode rays?
Cathode rays are found in vacuum tubes. Scientists are able to view them when they are a negative cathode because they emit a light and can glow.
Which type of motion does cathode rays create?
Cathode rays create straight-line motion. They are streams of electrons that travel in a straight line from the cathode to the anode in a vacuum tube.
What would happen to the deflection of the cathode ray if the particle in the rays were heavier?
deflect more
Streams of electrons directed by a vacuum tube?
I think the answer is 'Cathode Rays'
How do cathode rays form?
Cathode rays are the emission of free electrons form the negative pole of an electric circuit. To get this to happen you need to warm the cathode and place it in a vacuum tube with a high voltage across it. The electron then jump form the cathode and fly across the empty tube to the anode (positive end). They may be bent by magnetic fields in flight.
Why is the cathode-ray tube in figure 4 connected to a vacuum pump?
A Cathode-ray tube is a vacuum that is used to get the air out. Cathode rays (electrons) cannot penetrate through any significant amount of air.
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.
What are streams of electrons directed by a vacuum called?
i think it is known as cathode rays, but i am not sure
How do charged plates affect the path of cathode rays?
The electron particles in cathode rays have a negative charge. So if a plate is positively charged, it would attract the cathode rays, and if it was negatively charged, it would repel the rays.
How do charged plates affect the plates of cathode rays?
The electron particles in cathode rays have a negative charge. So if a plate is positively charged, it would attract the cathode rays, and if it was negatively charged, it would repel the rays.
Why can cathode rays be observed and manipulated within a vacuum tube and not in air?
Actually, they cannot be observed even in a vacuum tube. In a CRT, or cathode ray tube, electrons (this is what "cathode rays" are) are emitted by a heated cathode that is at a negative potential, accelerated by being attracted to a very high positive voltage and magnetically steered so they impact a screen coated with phosphors. When the beam hits the phosphor coating, the phosphor emits visible light. This is what we see, not the electron beam itself. Electrons are free to travel in a vacuum, but they are quickly stopped in air by interacting with all the atoms of gas floating about. This is one reason the air is removed in a CRT, not to mention the hot cathode would almost instantly burn out if air (containing oxygen) were present.
