The spectrum shows emission lines of calcium in the H and K bands.

Its visible spectrum does not show any features, although there is a small departure from the linearity near 0.8 μm.

The spectrum shows that the content is from 50 to 100% helium.

Their spectrum should show absorption lines due to the cloud, and the Doppler shift will give us the speed.

The spectrum shows peculiar features caused by chemical stratification of the outer atmosphere.

The lower case 'v' in the stellar class indicates that the spectrum shows signs of variation.

So moving the mirror a total distance of the wavelength of light means the spectra will show one complete cycle.

When the nova was discovered, its spectrum showed material moving at a high speed towards Earth.

The spectrum of this object shows the signature of mafic minerals.

The smooth spectra also showed a thin, jagged peak.
