An electromagnetic radiation has an energy 14.4eV. To which region of electromagnetic spectrum belongs to

Options

A. UV region
B. visible region
C. IR rays region
D. `gamma` ray region

Answer

To determine the region of the electromagnetic spectrum to which the electromagnetic radiation with an energy of 14.4 eV belongs, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Energy Value**: We are given that the energy of the electromagnetic radiation is 14.4 eV.

2. **Understand the Electromagnetic Spectrum**: The electromagnetic spectrum is divided into different regions based on the energy of the radiation. The key regions include:
- Infrared (IR): Less than 1.6 eV
- Visible Light: Approximately 1.6 eV to 3.1 eV
- Ultraviolet (UV): Approximately 3.1 eV to around 3000 eV (3 keV)
- X-rays: Higher than UV, typically from 100 eV to 100 keV
- Gamma rays: Higher than X-rays, starting from around 100 keV and going to infinity

3. **Compare the Given Energy with the Regions**:
- The energy of 14.4 eV is greater than the maximum energy of the visible light region (3.1 eV).
- It is also less than the energy range of X-rays (which starts from around 100 eV).

4. **Conclusion**: Since 14.4 eV is greater than 3.1 eV and less than 100 eV, it falls into the ultraviolet (UV) region of the electromagnetic spectrum.

5. **Final Answer**: The electromagnetic radiation with an energy of 14.4 eV belongs to the ultraviolet (UV) region of the electromagnetic spectrum.
