spectra

The first JWST data include not just pretty pictures but also spectra, measurements of how much light an object emits at various wavelengths.

Tiny strands of über-durable spectra integrated into the upper kept our feet from moving excessively, and five-millimeter rubber lugs gripped all manner of sloppy surfaces.

Just turn down the lights, or place filters on LEDs that narrow the spectra of light they shine down.

The spectra of light coming from spiral nebulae was similar enough to that of the Milky Way that they could be similar objects, he maintained.

It includes light spectra for more than three million astronomical objects.

Stars also have distinctive spectra, determined by their temperature, size, and, to a lesser degree, their chemistry.

The result is a mosaic of spectra, covering up to 60 different regions.

The spectra of the metals of the alkaline earths are equally definite, though more complicated.

It is science when the astronomer compares the spectrum of the sun with the spectra of various metals in the laboratory.

Gamma-ray spectra are collected all day, first from a sample, then from its accompanying standard.

The two gamma-ray spectra you obtain look like those in the figure on the opposite page.

Spectra of stars, per contra, appear relatively simple, since their feeble light is insufficient to bring out faint details.
