The primary difference between $X$-rays and $\gamma$-rays is that:
- AThe wavelength of $\gamma$-rays is shorter than that of $X$-rays.
- B$\gamma$-rays originate from the nucleus,while $X$-rays originate from the outer part of the atom.
- CThe ionizing power of $\gamma$-rays is higher than that of $X$-rays.
