Hydrogen light spectrum wavelengths
Web15 mei 2024 · When a visible spectrum travels through a prism, the light gets separated into a spectrum of colors of different wavelengths. The violet color has the shortest wavelength of around 380 nm, and the red color has the longest wavelength of around 700 nm. Our eyes can detect the outer-most layer of the sun, the corona, in visible light. WebUltraviolet astronomy is also best done from space. Electromagnetic radiation with wavelengths between roughly 400 and 700 nm is called visible light because these are the waves that human vision can perceive. This is also the band of the electromagnetic spectrum that most readily reaches Earth’s surface.
