What is the nature of particle constituting positive rays?
Answer: The positive rays originating from the anode consist of positive ions. The mass of these ions depend upon the gas used in discharge tube.
What are positive rays in physics?
Definition of positive ray : a stream of positively charged ions moving toward the cathode in a discharge tube.
What is the origin of positive rays?
Ans :- These rays were found to consist of positively charged particles and were called anode rays or positive rays or canal rays. These rays are believed to be produced as a result of the knock out of the electrons from the gaseous atoms by the bombardment of high speed electrons of the cathode rays on them.
What are cathode rays and positive rays?
Thomson called them positive rays. When an electric discharge is passed through the gas, some of the molecules of the gas ionised and produce cathode rays….Structure of the Atom.

How are positive rays produced in discharge tube?
The process by which anode rays are formed in a gas-discharge anode ray tube is as follows. These collide with atoms of the gas, knocking electrons off of them and creating more positive ions. These ions and electrons in turn strike more atoms, creating more positive ions in a chain reaction.
What are positive rays called?
An anode ray (also positive ray or canal ray) is a beam of positive ions that is created by certain types of gas-discharge tubes.
Which rays are positively charged particles?
α-rays are positively charged particles.
Why positive rays are not to be called as anode rays?
positive rays are not called anode rays because they unlike cathode rays (which originate from the cathode) these are not produced by the anode.
Do anode rays originate from anode?
The streams of positively charged particles are called anode rays or positive rays or canal rays. Anode rays are not emitted from the anode but are produced in the space between the anode and the cathode.
Is cathode ray positive or negative?
Cathode rays are a beam of negatively charged electrons traveling from the negative end of an electrode to the positive end within a vacuum, across a potential difference between the electrodes. How Do the Cathode Rays Work? The cathode is a negative electrode, Anode is the positive electrode.
Is cathode positive or negative?
A cathode is a negative sided electrode. An anode is a positive sided electrode. The cathode acts as an electron acceptor. The anode acts as an electron donor.
How will you demonstrate that anode rays carry positive charge?
Anode rays consist of material particles. Anode rays are deflected by electric field towards negatively charged plate. This indicates that they are positively charged.
What is the nature of positive rays produced in a vacuum?
the nature of the gas filled The nature of positive rays produced in a vacuum discharge tube depends upon the nature of the gas filled. The positive rays consists of positive ions obtained by removing one or more electrons from gas molecules. Answer verified by Toppr
What is the charge to mass ratio of cathode ray tube?
When the cathode ray tube contained hydrogen gas, the particles of the canal rays obtained were the lightest and their charge to mass ratio (e/m ratio) was the highest. Rutherford showed that these particles were identical to the hydrogen ion (hydrogen atom from which one electron has been removed).
What is an anode ray?
On passing high voltage between the electrodes of a discharge tube it was found that some rays were coming from the side of the anode which passed through the holes in the cathode. These anode rays (canal rays) consisted of positively charged particles formed by ionization of gas molecules by the cathode rays.
What is a positron particle?
…discovered the particle called the positron. Positrons are very much like electrons: they have the same mass and the same…. Stable in a vacuum, positrons quickly react with the electrons of ordinary matter by annihilation to produce gamma radiation.
