St . Elmo's fire was observed and its optical spectrum recorded during a University of Alaska research flight over the Amazon in 1995 to study sprites.

They used an optical spectrum taken with the Keck Telescope toward the optical afterglow of GRB 970508 to establish that gamma-ray bursts were at cosmological distances.
23.
In the early 1990s, Fayer realized that a great leap could be taken if the experiments could be extended to the infrared regions of the optical spectrum.

You might mention the actual percent reflectivity of untarnish silver in the optical spectrum, and also the use of transparent quartz overcoats on silver mirrors to prevent tarnishing.
25.
Some ONTs can receive a broad range of optical spectrum from 1480 nm to 1580 nm, so making the 10G-PON downstream signal visible to G-PON receivers.

I'd like to print it out accompanied by the articles about Radio waves, Microwave, Infrared, Optical spectrum, Ultraviolet, X-ray and Gamma ray.

"' Stationary-wave integrated Fourier transform spectrometry ( SWIFTS ) "'is an analytical technique used for measuring the distribution of light across an optical spectrum.
28.
This is a common type of active galaxy known as a LINER, which means that the optical spectrum is dominated by emission lines from gases in low energy ionization states.

As each member of the star system approaches the observer in turn, the absorption lines of that star are shifted toward the blue end of the optical spectrum by the Doppler effect.
