Name the em waves which are produced during radioactive decay of a nucleus. Write their frequency range.

Explanation

**Step-by-Step Solution:**

1. **Identify the EM Waves Produced During Radioactive Decay:**
- During the process of radioactive decay, the primary electromagnetic (EM) waves produced are **gamma rays**. These are high-energy photons emitted from the nucleus of an atom when it undergoes decay.

2. **Understand the Nature of Gamma Rays:**
- Gamma rays are a form of electromagnetic radiation that have very high energy and short wavelengths. They are produced as a result of nuclear reactions, including radioactive decay.
