The types of electromagnetic radiations that make up the electromagnetic spectrum are radio waves, microwaves, infrared light, visible, ultraviolet light, X-rays and gamma-rays. Most electromagnetic radiations from space are unable to reach the Earth's surface because the earth's atmosphere is opaque to most wavelengths of the electromagnetic spectrum.
Electromagnetic radiation with wavelengths between roughly 400 and 700 nm is called visible light. The visible light or spectrum constitutes part of the electromagnetic spectrum that we can see with our eyes. This is also the band of the electromagnetic spectrum that most readily reaches Earth’s surface. Visible light penetrates Earth’s atmosphere effectively, except when it is temporarily blocked by clouds.
