Here's why:
* Electromagnetic Spectrum: X-rays fall on the electromagnetic spectrum between ultraviolet light and gamma rays.
* Energy Levels: The energy of electromagnetic radiation is directly related to its frequency. Higher frequencies correspond to higher energy. Since X-rays have a higher frequency than visible light, they have higher energy.
* Penetrating Power: The high energy of X-rays allows them to penetrate materials that visible light can't, making them useful for medical imaging and industrial applications.
In summary: X-rays are not low energy. They are high-energy electromagnetic radiation with significant penetrating power.
