NEETPhysicsDual Nature of Radiation and MatterMCQ+4 / −1
Which of the following is not the property of cathode rays ?
  1. A
    In produces heating effect
  2. B
    It does not deflect in electric field
  3. C
    It casts shadow
  4. D
    It produces fluorscence.

Correct answer: B

Cathode rays are basically negatively charged particles (electrons). If the cathode rays are allowed to pass between two plates kept at a difference of potential, the rays are found to be deflected from the rectilinear path. The direction of deflection shows that the rays carry negative charges.
