Spectroradiometry is a technique in Earth and planetary remote sensing, which makes use of light behaviour, specifically how light energy is reflected, emitted, and scattered by substances, to explore their properties in the electromagnetic (light) spectrum and identify or differentiate between them.

Radiolab airs as a one-hour broadcast each week while its podcast releases new episodes of varying lengths usually biweekly. For a few years, the Radiolab podcast feed featured a full-hour episode every six weeks, announced by the hosts as Radiolab: The Podcast , interspersed with two shorter pieces known as "shorts."
The last two episodes were planned to air on Discovery Channel, but a last-minute schedule change landed them on Science. Exploring Time – A two-hour television documentary miniseries about natural time scale changes; Extreme Smuggling; Futurecar – New technology may be used to create advanced cars and sometimes funny cars in the future.
Artificial sunlight is useful in treating and preventing seasonal affective disorder (also known as winter depression, which causes depression symptoms specifically in winter), [3] and delayed sleep phase syndrome, in which the circadian rhythm (the rhythmic alternation between daylight and nighttime behavior and bodily states) is disturbed and the person falls asleep much later than he or she ...
Cosmos: A Spacetime Odyssey is a 2014 American science documentary television series. [2] The show is a follow-up to the 1980 television series Cosmos: A Personal Voyage, which was presented by Carl Sagan on the Public Broadcasting Service and is considered a milestone for scientific documentaries.
Star Gazers (formerly known as Jack Horkheimer: Star Hustler and later Jack Horkheimer: Star Gazer) is a short astronomy show on American public television previously hosted by Jack Horkheimer, executive director of the Miami Space Transit Planetarium.
Diagram of part of the electromagnetic spectrum. Far infrared (FIR) or long wave refers to a specific range within the infrared spectrum of electromagnetic radiation.It encompasses radiation with wavelengths ranging from 15 μm (micrometers) to 1 mm, which corresponds to a frequency range of approximately 20 THz to 300 GHz.
Second, the emission spectrum of the same lamp shining through the sample is measured (this is called the "sample spectrum"). The sample will absorb some of the light, causing the spectra to be different. The ratio of the "sample spectrum" to the "background spectrum" is directly related to the sample's absorption spectrum.
