Why are anode rays called canal rays?
Anode rays are positively charged .so they are bend towards perforated cathode which is negatively charged and pass through them.since they have passed through canals or holes by producing fluorescence. Therefore they are known as canal rays.
Why is concave lens called a negative lens?
A concave lens is called a negative lens because it causes light rays passing through it to diverge, or spread out. This is in contrast to a convex lens, which converges light rays and is called a positive lens. The negative or positive designation refers to the effect the lens has on the light rays.
What is light rays coming in called?
Light rays coming in are called incident light rays.
What is the light rays that bounce back called?
The light rays that bounce back are called reflected light rays.
What are the electromagnetic waves with the shortest wavelengths and the highest frequency called?
Gamma Rays
What are canal rays and why they are called canal rays?
Canal rays, also known as positive rays, are streams of positively charged particles, typically ions or atoms, that are emitted from the anode during gas discharge in a cathode ray tube. They are called "canal rays" because they travel through narrow channels or "canals" formed in the gas, which is ionized by the electrons emitted from the cathode. The discovery of canal rays helped in understanding the nature of atomic structure and led to the identification of different elements based on their positive ion emissions.
What are canal rays?
Canal rays, sometimes called anode rays, were first observed in by Eugen Goldstein in 1886. These rays are streams of positive ions in a rarefied gas and have a higher mass compared to electrons.
Why are anode rays called canal rays?
Anode rays are positively charged .so they are bend towards perforated cathode which is negatively charged and pass through them.since they have passed through canals or holes by producing fluorescence. Therefore they are known as canal rays.
Why anode rays also known as canal rays?
Anode rays are also known as canal rays because they were discovered to be positively charged particles produced in a cathode tube when the cathode rays strike a gas at low pressure. The particles travel in the opposite direction of cathode rays and move towards the anode or positive electrode, hence the name "anode rays."
What are the properties of canal rays?
Canal rays, or positive rays, are streams of positively charged particles, typically ions, produced in a discharge tube. They travel in straight lines, are deflected by electric and magnetic fields in a manner opposite to that of electrons, indicating their positive charge. Canal rays also have a mass, which varies depending on the type of ion, and can produce fluorescence when they strike certain materials. Additionally, they are observed to have a higher mass-to-charge ratio than electrons.
How does the mass to charge ratio of cathode rays compare to that of anode rays?
it varies because charge to mass ratio of positive rays depends upon gases used in the discharge tube.its varies from gas to gas.
What is the old name of cathode rays?
canal rays
Who discovered canal rays?
Canal rays were discovered by Sir William Crookes in 1870. He observed these rays while studying the behavior of cathode rays in a vacuum tube.
Why the nature of canal rays depends upon the nature of the gas in the discharge tube?
The nature of canal rays, or positive rays, depends on the gas in the discharge tube because these rays are composed of positively charged particles (often ions) that are produced when gas atoms are ionized. Different gases have distinct atomic structures, leading to the emission of different types of positive ions when the gas is ionized. Consequently, the mass, charge, and behavior of the canal rays will vary based on the specific gas used, affecting their properties such as speed and deflection in electric and magnetic fields. This variability is crucial for applications in fields like mass spectrometry and atomic research.
What is the difference between electron beam and cathod rays?
X ray is light and belongs to the family of electromagnetic waves. It is said to be photon whose rest mass is zero. X ray does not have charge.Electron is considered as particle which has mass, of 9.1 x10 -31 kg.Electrons posses negative charge that equals 1.602 x 10 -19 C
