Which is not true with respect to cathode rays?
Correct answer: C. Move with speed as that of light
- A. A stream of electron
- B. Charged particles
- C. Move with speed as that of light
- D. Can be deflected by magnetic fields
Explanation
The statement that cathode rays move with the speed of light is not true. Cathode rays, which are streams of electrons, do not move at the speed of light. They do, however, have high velocities, typically a significant fraction of the speed of light.

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.
