what radiation has the highest frequency
The only region in the entire electromagnetic spectrum that our eyes are sensitive to is the visible region. Gamma rays have the shortest wavelengths, < 0.01 nanometers (about the size of an atomic nucleus). This is the highest frequency and most energetic region of the electromagnetic spectrum. Gamma rays can result from nuclear reactions and from processes taking place in objects such as pulsars, quasars, and black holes. X-rays range in wavelength from 0.01 â 10 nm (about the size of an atom).
