Which of the following radiations `alpha,beta and gamma` are :
similar to x-rays ?

Explanation

To determine which of the following radiations (alpha, beta, and gamma) are similar to X-rays, we need to analyze the properties of each type of radiation.

### Step-by-Step Solution:

1. **Understand X-rays**:
- X-rays are a form of electromagnetic radiation.
- They travel at the speed of light (approximately \(3 \times 10^8\) m/s).
- X-rays do not require a medium to propagate.
