Answer:
a. 1028 angstrom.
Explanation:
Induced radioactivity will occur when a stable matter is exposed to radioactive rays of specific electromagnetic radiations. In the given case, a hydrogen atom will become radioactive by exposing to electromagnetic radiation of λ of 1028 Angstrom. The ground state energy of hydrogen atom will be 13.6 electron volts.
