The Spectrum Range, formerly gazetted as the Spectrum Mountains and the Rainbow Mountains, is a small mountain range in Cassiar Land District of northwestern British Columbia, Canada. Located at the southern end of the Tahltan Highland , it borders the Skeena Mountains in the east and the Boundary Ranges of the Coast Mountains in the west.

The optical atmospheric window is the optical portion of the electromagnetic spectrum that passes through the Earth's atmosphere, excluding its infrared part; [10] although, as mentioned before, the optical spectrum also includes the IR spectrum and thus the optical window could include the infrared window (8 – 14 μm), the latter is ...
Up until the 1940s, astronomers used optical telescopes to observe distant astronomical objects whose radiation reached the earth through the optical window. After that time, the development of radio telescopes gave rise to the more successful field of radio astronomy that is based on the analysis of observations made through the radio window.
Exile Hill is a volcanic feature associated with the Spectrum Range volcanic complex which in turn form part of the Northern Cordilleran Volcanic Province. It is a cinder cone that formed in the Pliocene period.
The Mess Creek Escarpment is a long, discontinuous cliff along Mess Creek in Cassiar Land District of northwestern British Columbia, Canada.It forms the east-central side of Mess Creek valley and consists of two segments separated about 5 kilometres (3.1 miles) by Walkout Creek valley.
Richat Structure by Shuttle Radar Topography Mission (SRTM). Instead of being a meteorite impact, the landform is more likely to be a collapsed dome fold structure.. Remote sensing is used in the geological sciences as a data acquisition method complementary to field observation, because it allows mapping of geological characteristics of regions without physical contact with the areas being ...
UV-C radiation spans from 0.1μm to .28μm, UV-B from 0.28μm to 0.315μm, UV-A from 0.315μm to 0.4μm, the visible spectrum from 0.4μm to 0.7μm, and NIR arguably from 0.7μm to 5.0μm, beyond which the infrared is thermal. [1] Shortwave radiation is distinguished from longwave radiation.
