Electromagnetic Spectrum

Step 1: Understanding the Electromagnetic Spectrum
X-rays are a type of electromagnetic radiation with wavelengths shorter than ultraviolet rays but longer than gamma rays.
The electromagnetic spectrum covers a wide range of wavelengths, and X-rays are located between ultraviolet radiation and gamma rays.
Step 2: Explanation of Other Options
Option (a) is incorrect because X-rays lie between ultraviolet and gamma rays, not between visible and ultraviolet regions.
Option (b) is incorrect because X-rays are not located between short and long radio waves.
Radio waves have much longer wavelengths than X-rays.
Option (c) is incorrect because X-rays lie between ultraviolet and gamma rays, not between short radio waves and visible light.
Step 3: Conclusion Thus, X-rays lie between gamma rays and ultraviolet radiation in the electromagnetic spectrum.
