The wavelength of x-rays is of the order of

Options

A. `10^(-4)` m
B. `10^(-6)` m
C. `10^(-8)` m
D. `10^(-10)` m

Answer

To determine the wavelength of X-rays, we can follow these steps:

### Step-by-Step Solution

1. **Understanding Electromagnetic Waves**:
- X-rays are a type of electromagnetic wave. The electromagnetic spectrum includes various types of waves, arranged by their wavelength.

2. **Identifying the Electromagnetic Spectrum**:
- The electromagnetic spectrum is organized from long wavelengths to short wavelengths:
- Radio waves → Microwaves → Infrared → Visible light → Ultraviolet (UV) → X-rays → Gamma rays.

3. **Wavelength Range of X-rays**:
- X-rays have shorter wavelengths compared to visible light and UV rays. They are typically found in the range of 0.01 nm to 10 nm.

4. **Scientific Notation for Wavelength**:
- In scientific notation, this range can be expressed as:
- 10^-12 m (for gamma rays) to 10^-10 m (for X-rays).

5. **Conclusion**:
- Therefore, the wavelength of X-rays is of the order of 10^-10 meters, which is equivalent to 1 angstrom (Å).

### Final Answer:
The wavelength of X-rays is of the order of \( 10^{-10} \) meters (or 1 angstrom).
