    Since this includes the visible and near-infrared portions of the spectrum, silicon can be used as a solar cell, with collection efficiencies near 20% of the impinging photons. For the mid and far infrared portions of the optical spectrum, undoped silicon is transparent. As free carriers are added, the transmission diminishes.5/5(5).

High purity germanium remains the material of choice for the detection of photons in the range of MeV or higher, down to the hard X-ray range. Since the operation of HPGe-based detectors is possible only at or below the liquid nitrogen temperature, their advantage is mainly the resolution, which matches the Fano factor if appropriate cooled electronic readout is by: 1.

Astronomy []. Def. astronomy using observations using telescopes and recording media that capture visible light is called optical astronomy. Def. astronomy using infrared, visible and/or ultraviolet wavelengths is called optical astronomy.

Radiation [] "The radio quasar 3C underwent an exceptional optical outburst lasting more than 1 year and culminating in spring. Relation between Absorption and Emission Spectra. Fluorescence and phosphorescence come at lower energy than absorption (the excitation energy). As shown in Figure \(\PageIndex{1}\), in absorption, wavelength λ 0 corresponds to a transition from the ground vibrational level of S 0 to the lowest vibrational level of S absorption, the.

Theoretical rays []. Def. a "beam of light or radiation" is called a ray. Def. an action or process of throwing or sending out a traveling ray in a line, beam, or stream of small cross section is called radiation. The term radiation is often used to refer to the ray itself.

Def. “[t]he shooting forth of anything from a point or surface, like the diverging rays of light; as, the radiation of.
