positive rays are produced
Correct answer: B. By the bombardment of cathode rays on gas molecules
- A. By burning of gas
- B. By the bombardment of cathode rays on gas molecules
- C. By cooling of the gas
- D. From the anode like cathode rays, produced from cathode
Explanation
Positive rays, also known as canal rays or anode rays, are produced by the bombardment of cathode rays on gas molecules. When cathode rays strike gas molecules, they can ionize the gas atoms, creating positive ions. These positive ions are then attracted towards a negatively charged electrode (anode), producing positive rays. Option (b) By the bombardment of cathode rays on gas molecules is the correct statement

About Atomic Structure
Atomic structure covers the discovery of the proton, Planck's quantum theory, hydrogen emission spectra and the evidence for quantized energy levels. You will use quantum numbers to describe orbitals, distinguish s, p, d and f orbital shapes, and write electronic configurations, including the correct order of electron filling.
