Penetration Power:

* Gamma rays have higher energy levels than X-rays, typically in the range of MeV (megaelectron volts). This high energy allows them to penetrate through matter more easily.

* X-rays have lower energy levels, typically in the range of keV (kiloelectron volts). They have less penetration power than gamma rays.

Other Factors:

* Wavelength: Gamma rays have shorter wavelengths than X-rays.

* Frequency: Gamma rays have higher frequencies than X-rays.

Applications:

* Gamma rays are used in medical imaging, radiation therapy, and industrial applications due to their high penetration power.

* X-rays are used in medical imaging, airport security, and industrial inspection.

In Summary:

Gamma rays have a higher energy level, shorter wavelength, and higher frequency than X-rays, making them more penetrating.
