Understanding Electromagnetic Radiation Sources
Electromagnetic waves vary in wavelength across different sources. To comprehend the correct order of wavelengths produced by various radiation sources, we can analyze each option provided.
Types of Radiation Sources:
- Radioactive Source: Emits gamma rays, which have very short wavelengths (high frequency).
- X-ray Tube: Produces X-rays with shorter wavelengths than visible light but longer than gamma rays.
- Sodium Lamp: Emits light in the visible spectrum, specifically in the yellow-orange range, with longer wavelengths than X-rays.
- Magnetron Valve: Primarily used in microwave ovens, it generates microwaves with even longer wavelengths than visible light.
Wavelength Order from Shortest to Longest:
- Gamma Rays (from Radioactive Source)
- X-rays (from X-ray Tube)
- Visible Light (from Sodium Lamp)
- Microwaves (from Magnetron Valve)
Correct Sequence Explained:
In option B, the order is:
1. Radioactive Source: Produces the shortest wavelengths (gamma rays).
2. X-ray Tube: Produces X-rays, which are longer than gamma rays but shorter than visible light.
3. Sodium Lamp: Emits visible light with longer wavelengths.
4. Magnetron Valve: Produces microwaves, which have the longest wavelengths in this grouping.
This sequence follows the increasing order of wavelengths, confirming that option B is indeed the correct answer.
Conclusion:
Understanding the properties of each radiation source helps in determining the correct sequence of electromagnetic wave wavelengths. This knowledge is essential for various applications in physics and medical imaging, especially relevant in NEET preparation.
