BeauAnode rays are called canal rays because they were initially discovered using a modified version of a cathode ray tube called a "canal ray tube." In these tubes, positive particles (anode rays) were produced and focused into a beam through a narrow canal, hence the name "canal rays."

Why positive rays called canal rays?
Positive rays are called canal rays because they are positively charged particles emitted by the anode and accelerated through a small canal or channel in the cathode of a cathode ray tube. These rays were discovered by Eugen Goldstein and were later studied by J.J. Thomson.
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 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 role does the negative electrode play in the operation of an x-ray tube?
The negative electrode, also known as the cathode, in an x-ray tube is responsible for producing a stream of electrons that are accelerated towards the positive electrode, or anode. These electrons collide with the anode, generating x-rays through a process called bremsstrahlung radiation. In summary, the negative electrode plays a crucial role in initiating the production of x-rays in an x-ray tube.
Why cathode rays are negatively charged?
Cathode rays are negatively charged because they are composed of electrons, which have a negative charge. When a high voltage is applied to the cathode in a vacuum tube, electrons are emitted from the cathode and accelerated towards the anode, creating a beam of negatively charged particles known as cathode rays.
