Question 44

Electromagnetic Spectrum

The difference between x-rays and gamma rays is that

  1. A.x-rays arise from energy changes in the electronic structure of atoms while gamma rays come from the nucleus.
  2. B.x-rays are electromagnetic radiations while gamma rays are negatively charged radiations.
  3. C.x-rays have higher frequencies than gamma rays.
  4. D.x-rays are more penetrating than gamma rays.
Show the answer and explanation

Answer: A (x-rays arise from energy changes in the electronic structure of atoms while gamma rays come from the nucleus.)

Explanation

Both are electromagnetic waves; X-rays come from electron energy changes in atoms, gamma rays from the nucleus.
