The electromagnetic radiation which has the smallest wavelength are
- X-rays
- Gamma rays
- Ultraviolet rays
- Microwaves
The Correct Option is B
Solution and Explanation
To determine which electromagnetic radiation has the smallest wavelength, we need to understand the electromagnetic spectrum. The electromagnetic spectrum is a range of all types of electromagnetic radiation, which are categorized by their wavelength and frequency.
The order of the electromagnetic spectrum from the longest wavelength to the shortest wavelength is:
- Radio Waves
- Microwaves
- Infrared Radiation
- Visible Light
- Ultraviolet Radiation
- X-rays
- Gamma Rays
As per this order, gamma rays have the smallest wavelength among the given options. They are located at the end of the spectrum with the shortest wavelengths and the highest frequencies.
Explanation for each option:
- X-rays: These have shorter wavelengths than ultraviolet rays and microwaves but are longer than gamma rays.
- Gamma rays: These have the shortest wavelengths and the highest energy in the electromagnetic spectrum, making them the correct answer.
- Ultraviolet rays: These have shorter wavelengths than visible light but longer than X-rays.
- Microwaves: These have much longer wavelengths compared to visible light, ultraviolet, X-rays, and gamma rays.
Therefore, the correct answer is Gamma rays because they possess the smallest wavelength in the electromagnetic spectrum.
Conclusion: Understanding the order of the electromagnetic spectrum helps in determining the relative wavelength of various types of radiation. Gamma rays, being at the extreme end of the spectrum, have the smallest wavelengths.
