gamma ray
Highest-frequency light
Gamma rays are the highest-energy form of electromagnetic radiation, produced by radioactive decay, nuclear reactions, and cosmic events.
They penetrate most materials and can damage living tissue, making them useful in cancer treatment and sterilization but hazardous with prolonged exposure.
Gamma rays from the sun are absorbed by Earth's atmosphere.
