Answer:
Electromagnetic spectrum
Step-by-step explanation:
The electromagnetic spectrum consists of electromagnetic radiation of all possible wavelengths.
It ranges roughly from wavelengths of 1 fm (10⁻¹⁵ m, gamma rays) to those of 1 Mm (10⁸ m, super low frequency waves).
Visible light occurs in the 400 nm – 700 nm region of the electromagnetic spectrum.
