Name the part of the electromagnetic spectrum which is :
Produced by bombarding a metal target with high electrons.

Explanation

To solve the question, we need to identify the part of the electromagnetic spectrum that is produced when a metal target is bombarded with high-energy electrons.

### Step-by-Step Solution:

1. **Understanding the Process**: When high-energy electrons collide with a metal target, they can transfer energy to the atoms in the metal. This process can lead to the emission of electromagnetic radiation.

2. **Identifying the Radiation**: The type of radiation produced in this scenario is known as X-rays. X-rays are a form of electromagnetic radiation that has a very short wavelength and high frequency.
