* Gamma rays: These are the highest-energy, shortest-wavelength waves on the electromagnetic spectrum.
* X-rays: These waves have wavelengths shorter than ultraviolet rays.
* Ultraviolet (UV) rays: These waves are shorter than visible light.
It's important to note that while these waves reach Earth, they can be harmful to living organisms. Gamma and X-rays are ionizing radiation, meaning they can damage cells. Excessive exposure to UV rays can cause sunburns and skin cancer.
