Light year and wavelength
NettetElectromagnetic waves are typically described by any of the following three physical properties: the frequency f, wavelength λ, or photon energy E. Frequencies observed in astronomy range from 2.4 × 1023 Hz (1 GeV gamma rays) down to the local plasma frequency of the ionized interstellar medium (~1 kHz). Nettet15. sep. 2024 · Ultraviolet (UV) light falls in the range of the EM spectrum between visible light and X-rays. It has frequencies of about 8 × 10 14 to 3 × 10 16 cycles per second, or hertz (Hz), and...

NettetWavelengths of light range from about 400 nm at the violet end of the spectrum to 700 nm at the red end ( see table). (The limits of the visible spectrum are not sharply defined but vary among individuals; there is some extended visibility for high-intensity light.) At shorter wavelengths the electromagnetic spectrum extends to the ultraviolet ... Nettet25. des. 2015 · The wavelength is, like you say, the distance between minima or maxima of the electric field in the wave. For things that we call "light" this is usually somewhere in the range of 100 nm to 10 um. If you make a 632.8 nm HeNe laser, the output wavelength will be 632.8 nm, no matter how long a path you propagate the beam through.
Nettet18. mai 2024 · For much greater distances — interstellar distances — astronomers use light years. A light year is the distance a photon of light travels in one year, which is about 6 trillion miles (9 trillion kilometers, or 63,000 AU). Nettet13. sep. 2024 · Floris. 118k 13 218 388. Add a comment. 1. Colour temperature is related to black-body radiation, in theory the distribution of wavelengths of a light source of a certain colour temperature should resemble that of a black body of that temperature. So colour temperature is not exactly related to a wavelength, but to a distribution of …
