WebElectromagnetic Spectrum Diagram The Electromagnetic Spectrum. Image Credit: NASA The electromagnetic spectrum is comprised of all frequencies of electromagnetic radiation that propagate energy and travel through space in the form of waves. Longer wavelengths with lower frequencies make up the radio spectrum. WebIt ranges from 300 to 700 nm. Option (C): UV radiation is a type of radiation that is non-ionizing in nature and emitted by the sun. Some other sources are halogens, lasers, etc. Hence, the correct answer is an option (B). Q.
