Name the parts of the electromagnetic spectrum which is
used as a diagnostic tool in medicine.
Write in brief, how these waves can be produced.

Explanation

### Step-by-Step Solution:

1. **Identify the Parts of the Electromagnetic Spectrum Used in Medicine:**
- The primary part of the electromagnetic spectrum used as a diagnostic tool in medicine is **X-rays**.

2. **Explain How X-rays are Produced:**
- X-rays can be produced by the **bombardment of high-energy electrons** onto a metal target, typically made of tungsten.
- When high-energy electrons collide with the metal target, they decelerate rapidly, which results in the emission of X-rays due to the conversion of kinetic energy into electromagnetic radiation.
