Q.  Consider the following differences between Gamma Rays and X rays:

1. Gamma rays have shorter wavelengths than the X-rays
2. Gamma rays are produced during nuclear decay by nuclei of atoms, whereas X-rays are produced by electrons

  Which of the above statements is/are correct?
Answer: Both 1 & 2
Notes: Both are correct statements
Both X-Rays and gamma rays refer to waves in the electromagnetic spectrum. While gamma rays are produced during nuclear decay by nuclei of atoms, X-rays are produced by electrons. Gamma rays have shorter wavelength than X- rays.
