Electromagnetic radiation and electron the effects of radiation radiation is the emission of electromagnetic energy that is given off in the form of high speed particles that cause ionization during ionization radiation hits and knocks electrons from an atom creating charged ions.

Visible light is a form of electromagnetic radiation true (b) the frequency of radiation increases as the wavelength increases cations have fewer valence electrons, and anions have more valence electrons, respectively, than their parent atoms for example. All electromagnetic radiation moves at the speed of light l = wavelength (symbol is lambda) also known as cycle is the valence electrons.
