Question

Gamma rays are produced by:
  1. A
    Heating of atoms
  2. B
    Vibrating electric dipoles
  3. C
    Nuclear transitions (radioactive decay)
    Correct
  4. D
    Accelerating electrons in a wire

Correct answer

Nuclear transitions (radioactive decay)

Explanation

Gamma rays originate from nuclear energy transitions (e.g., after alpha or beta decay) and have the highest frequency (lowest wavelength) in the EM spectrum — typically >10¹⁹ Hz.
